Obsolete Product.

This is a KIT. You must build it yourself. Functionality exceptional high

This is used by the Canor company themself, and for sale as a product also. Alladin1 is for power tubes. Alladin2 is for small signal tubes.

This is based on the Testers we bought in 2009 and 2010

You get supplied the working PCB, and the metal housing, from which you must build a tube tester yourself.
This is a KIT. You must build it yourself. Very compact circuitry, it works with an old Dell Notebook power supply that you can buy on Ebay for 10€. So no mains transformer is needed.
Price
5500 Deutschmark in 1995.
Below 100€ for the build guide on CD. 800€ for the electronic parts. The housing price depends a lot on what you want, but appr 200€ is the direction. So calculate with appr 1100 Euro.
from 2000...8000 depending on model and options.
For a price of 2400 US$ in 2012, it was the only girl in town at that time.
830US$ complete. (price of Jan 2018)
Price on Ronald's homepage, 250€ by Paypal. This includes all parts for the PCB + Software. You must buy yourself: An old Dell Notebook power supply , a case, and tube sockets.
Repair Support

They offer repairs still after 25 years. Provided they can buy replacement parts needed.

Believe it or not, but repairs are included in the service, only shipping costs are charged. Most repairs however are done via email contact. This is with free shipment of spare parts if needed. Wow...what a service!
Schematics

I recieved a message from the president.

Dear Mr. van de Walle, as Mr. Bigi told you over the phone we do not supply schematics of our products. This a Company policy since 1985 and up to now we had only elements to enforce it.

Best regards,
Maurizio Jacchia.

Resolution

16bit. Which is achieved by D/A converters originally intended for HiFi. Such have per Chip two inputs (stereo) and two outputs with 95dB channel separation. Moreover these have programmable sensitivity from 0..93dB. So you can measure low voltage without running into digital resolution loss problems like AT1000 has * . Perfect devices at it's time, and still today. So no compromised analog Single Chip inputs.

* See AT1000 box on the right.

12 Bit for Version V5 or higher. Though at small signal, the tester auto scales to more sensitivity. This gives an artificial 16bit result.
24 bit. This is incredible high. Make note, this required expensive hardware.

10bit, and no offset problems. However often it doesn't work out, as there are no programmable amplifiers used. Like the most sensitive range is 10mA.

Resolution is often much below 10bits. For instance 6SN7 tests in steps like this: 2550, 2650, 2750. The last two digits are always "50", so the last two digits are of no use. You may as well say 2500, 2600, 2700. That is 5 bits. Even worce with plate current of 12AX7. 1.1, 1.2, 1.3 etc. That are steps of 10%, and that is 3.5 bits.

14 bits/ 900k samples/sec. A 6dB PGA inside the controller is used to give an effective resolution of 15 bits

The AD converter is 10 bits, but is preceded by a programmable amplifier with scope ranges: 1x,2x,5x,….100x, allowing for accurate measurements from 10 uA to 200 mA. This makes the 10bits indeed totally sufficient.

Measurement range Anode
0...700V DC @ 250mA

Two ranges:
0-300V, 300V-600V,
maximal 300 mA

0..300V @ 50mA

75...495V

This is good and bad. Very good is the 495V.

What is bad: Below 75V not possible

0..750V @ 300mA

0..400 V @ 200 mA

Measurement range G1

0-100V. Max 5 mA. 0.025V resolution.

-17V….0.02V @ 20mA

This limits the tester to specific tubes only.
0-100V. 150V in Auto Bias.
0-170V

0..50V

This is not enough for large triodes like 300B

Measurement of grid (G1) current
Yes. This is done via a series resistor in the grid, and measure the voltage across it.
Yes
I had a 45 tube, which was tested with 32uA grid current by the AT1000. Then, on the AVO Mk4 (analog tester) it had only 4uA. I added a precision current meter in the grid circuit of the AT1000. Result: 3,7uA. That is 865% error for the AT1000. This tells me grid current is calculated, possibly from the change of anode current.
This is a new product. Final information follows.
No
Measurement range G2
0...700V DC @ 250mA
0-306 V, 60 mA

0..750V @ 300mA

The circuit is identical to the plate supply. It can also be used to supply the plate voltage for a twin-triode or a full-wave rectifier.

0..400 V @ 200 mA
Measurement range G3
It has no G3 option.
0...-100V. This I have only seen with the RoeTest. It can be used for special tubes, where you just need a second negative voltage.
 
It has no G3 option.
It has no G3 option.
It has no G3 option.
Measurement range Heater

Filament 0..24V 5A (Wow!) and Current measurement included.

Filament
two ranges:
0-20V, 5,5A
0-125 V, 600 mA

14V @ 1,2A
Too low for me..

Maximum 12,6 Volt.too Too low for me.

1.5V~27V regulated DC supply with a current capacity of at least 3A. One side of the heater supply is always grounded.

0..15 V @ 1A. It is possible to use an external heater supply for both directly as well as indirectly heated tubes

HARDWARE

Shorts test between electrodes

This can bes dangerous. The day comes when you have a shorted tube, or make a mistake yourself. Wil the tester blow up?

 

No

I had some bad tubes, and the tester switched off without damage. The previous owner told me, he had damage before from shorts.

Yes

No

The manufacturer says, when you buy Canor burn in equipment, any failures will be found before.

Yes

From some cases of shorted and mistakenly wrong connected tubes, I can say it works.

Yes

Sophisticated protection circuits against various kind of shorts (HV to gnd, HV to grid, HV to filament, etc.)

No

Cathode to heater Leakage


(this is a hum source in amplifiers)

Don't know, but when I have time I will try, if the tester rejects such a tube.
     
Cathode to ground current check with a pass/fail threshold. Due to the limitation of ADC resolution the step is about 10uA. Not great but enough for a pass/fail test. The test voltage is selectable between 50V or 100V
 
Gas test
No, See above, because a gassy tube tends to short violently at higher voltage.

Yes

Yes
This is a new product. Final information follows.
No, See above, because a gassy tube tends to short violently at higher voltage.
Hazard Lamp. An LED costs 10 cents only. With 400Volt unprotected at the sockets, this is invested at the right place.

Very good thing.

Same principle as with Funke Testers.

AT1000 scores very high here. There is a lot of noise coming from the tester itself though.

No
No
Tester can select tube connections itself.
No
Yes
It can it connect any tube what so ever. It can also find out connections of an unknown tube by software.
No. Only such tubes the octal and noval base is wired for.
Only Plate, Cathode and 1st grid. Several tubes can not be tested, and need socket adapters.

Hardware Quality

Hardware is very good. No fan. Perfect :)

What I like, there is almost no SMD stuff in there. That makes it all a lot easier.

Depends on yourself. Service is convenient, due to modular construction.

Very good.

The Fan is definitely MUCH too loud. It is really a releigh to switch the machine off.

Very good
Very good
Updates

No.

Version 2.1 for DOS is available from the Audiomatica Website, but this is not an update, it is very old.

You download the software for free.

Software is not compatible with very old models.

No

Updates. What updates?

Yes

regularly, download for free for registered users.

Software Improvement

One major bug, see below. For the rest, I found nothing that needed improvement. Such a result after 25 years is more than magnificent.

Yes.

The software creator is actively working on things which can be added or improved.

Note: Very old hardware can not run all newer software versions. Check this when buying an older hardware fro somebody.

No

To my persanal opinion this software is a collection of misstakes and errorz.

I reported many issues. Amplitrex is not interested in improvements whatsoever. Don't think I never tried.

Yes

The software creator is actively working on things which can be added or improved.

 

Yes

User wishes of reported bugs have been regularly included in new GUI releases

Curve tracing

Yes

Curve charts are drawn the way they are supposed to look, right away. Scaling can be done afterwards, even if STORED curves. Wow!!!! This is an EXCELLENT Software job.

Yes

Options and possibilities are a dream, best of the best. Thinks like that justify the price fully.

Yes

Very good.

By default it draws only one curve. It needs a lot of trial before you have the curves drawn the way they look as in nornal datasheets. Even so, many users will not be capable of this, and give up.

Yes

Yes

Great care was given, to make give curves have original shape and functionality as in old datasheets.

Curves have appearane look like in old data sheets
Yes

At least no "Excel" look, so that is very good.

However, what is missing painfuly, is the classical curves as you see in any datasheet. So you can not construct a load line, for amplifier design.

I don't know

No.

They have "Excel" look.

Auto scaling is done strange, and can not be changed by the user.

Yes

No.

They have "Excel" look.

Tube parameters in operating point
Yes
Yes
  Yes
Yes
Yes
Tube parameters at multiple operating point

Yes

Such a remarkable feature! You can move a marker around in the curves, and you get all tube data at the specific operating point. Even in STORED curves you can do this later. So you use a 300B at 320V or at 480V, and that makes a LOT of difference. Amazing this part of the software works still under XP. Check here how to install that freeware.

Yes!



Added in 2017 by Helmut, after we talked about it. Please contact them, so find out if your hardware can run the update for this.

No. This is a pity. It can not be repeated often enough how severely transconductance, Gain, and Ri change at differrent working points. With the Roe-Test and SOFIA you can see that in one chart.
This is a new product. Final information follows.

Speed
Once the test is started, the curves are plotted after just seconds. Dynamical and static data is derived afterwards from the curves. Excellent feature: When you press"start" too quickly, curve plotting is auto delayed until the tube heater appears warmed up. This is done by monitoring the heater current draw. (I checked it with a scope) Great software job.
Canor writes it is very fast. It think it is a fraction faster than AT1000, but much slower than the Sofia.

The AT1000 is definitley too slow for me. When I use it for series testing, it becomes a very time consuming item, not fun to operate, and I avoid having to do so.

I don't know yet

Relatively slow

Review saved results

Another top class feature of this software. You can save the charts to disk, and you can change the scales afterwards. So you zoom in and out. Like test the tube from 0....600V. Another day, you can plot a curve from 0...200V only, it uses the original measurement.

Apart from that, you can also save it as bitmap.

Curves are not saved in graphic format, but internal results are saved. Like this, you can re-scale the curves later.

Apart from that, you can also save it as bitmap.

 

Not really. Main thing for me, the "test result" page and "tube curves" can not be saved electronically. A work around is use the pdf printer together and use the free "file hamster" from MOGWARE, to auto-save. Needless to say, SOFIA has this function integrated - of course.
Yes

Yes

And:

traced curves can be stored and examined later with a cursor

Software (1)

Pentode curves

Yes
Also Ultra Linear, or triode mode is possible
Yes
Also Ultra Linear, or triode mode is possible
It tests pentodes in triode mode. Problem Reported to Amplitrex, it seems technically possible, I have a working test version, but they never cared to follow up on it.
Yes

Yes

including Ultra Linear

Software (2)

Diode Curves in PC.

Yes
Yes
No, it can test only specific tubes, and no diodes on the list.

Amplitrex writes this can NOT be done, but I have found a way to do this.

Even for double diodes like 5U4G, I can draw both curves in one plot.

This is nice for me, when I can do this, but this shows how weak the software is, when users like me have to find out tricks, to be able to do things, which supposed to be impossible.

Yes

Yes

Software (3)

Can it test DHT tubes in "AC Heated " mode?

(When DC heated, if the tester draws a -1Volt line for a 300B, it equals in reality the -3,5 Volt line for AC heated, as in the tube data sheet. This is really a MAJOR problem)

No

 

Yes

DHT tubes are measured same as in the historical datasheets, when you use the function: "Simulate AC heating"

 

I don't know.

No.

I only report it here, for everbodies interest, but reporting it to Amplitrex has only resulted in a work-around advise, which worsk half way, partially wrong, and confusing.

Yes

Can be stored in the tube configuration files

I don't know.

Software (4)

Transconductance is tested by default at data sheet DC current?

Indirectly Yes

You can shift the marker in the tube curves, to ANY DC current, and in the "Result" window, Gm will be shown.

This is a bad issue with the AT1000. In the stand alone mode, Fixed Bias, the transconductance is represented in percent of "something". This "something" however, is the 100% datasheet value, which by itself can ONLY be measured at 100% plate current, or else you are measuring nonsense. And this is NOT what AT1000 is doing. So measuring nonsense.

This is a new product. Final information follows.

Indirectly Yes

A transconductance curves is provided, and you can look at the the specified DC current yourself then.

Software (5)

Emission Test

You can simulate it with set ups.
You can simulate it with set ups.
Though the software is telling you "Emission" and even shows this in percent, it is actually not measuring Emission at all. Just measures plate current and calls this Emission. That's a real mistake.
This is a new product. Final information follows.
You can derive it, and simulate it, but the tester itself will not do this for you and give the answer like for instance Funke W19 is doing.
Matching (6)

Yes.

Most excellent method used, which is a MASTER EXAMPLE of engineering quality. This method if HIGHLY RECOMMENDED to study, for every one who wants to make software for tube matching. So you can test 100 tubes, and the software tells you what tubes have CURVES that fit well to other tubes. Not just one or two test points, but full CURVES matching.

Helmut Weigel writes me, this is on his list, but a date is not known yet.
No. You have to decide for yourself if what you see is a good match or not. Specially since this tester has all data and options on board, and for what you pay, this is simply MISSING.
This is a new product. Final information follows.
No. You have to decide for yourself if what you see is a good match or not. Though matching by laying curves on each other is the best method I know, and it's only a matter of software.
Distortion Measurement
No
Yes, but to my opinion the method gives wrong results.
The more expensive "Pro" Version gives second and third harmonic
of course not
This is a new product. Final information follows.

Yes, up to the 5 th harmonic for resistive loads

Quality Control (8)
Yes
So the tester tells you if a tube is good or bad.

Yes
So the tester tells you if a tube is good or bad.

Indication is like red/yellow/green meter.

No

With "quality control" I expect the tester to tell me if a tube is good or bad. Add to this the plain errors with Emission Test and Transconductance test.

This is a new product. Final information follows.

Export of Test report
Yes. by hand or auto mode. Saves a bitmap
For the regular test reports, all you can do is print them.
This is a new product. Final information follows.

Yes, graphs can be stored as bmp files. Quick test data which includes all relevant tube parameters is collected in a printable report that can be shipped with tubes

The future of this software

The Microsoft Gods have decided not to allow direct access to the RS232 ports in all Windows Versions. For the Sofia however that is a problem, and it is extremely fast, and required real time port control, no delay by the Operating System. That is why even a DOS virtual machine does not work.

* With DOS BOX "Megabuild" Version it works under W7, with a well done DOS BOX installation.

As it also runs under Linux, we have an excellent reserve option here. "Green" score!

The software uses Microsoft internal modules, like MSCHART, etc, which is part of the microsoft Operating system. However these are very old microsoft modules, and I don't know what happens if one day, the Microsoft Gods decide, poeple "don't need this" any more. Them you can't install it any more on newer windows versions.

Knowing Microsoft, I see this as a risk.

This is a new product. Final information follows.

Regular free updates and improvements. On top of that there is an alternative free GUI available from an independent source (uTgui from Nick Barton) which runs under LINUX

Pro: No-compromise test range with excellent resolution. Can do full power testing, monitoring tube data. Or charts in impulse mode. Very professional software, with normal looking tube curves, same as old datasheets. (Example here, scroll down)

Contra: You can only install it when you understand MSDOS.

Pro: This products is alive! Each newer version fills this matrix with more green boxes. Incredible complete tube data base. Excellent email support. Also Helmut contacts me to inform me about new features.

When you are very technical and when you can build something, you should have this machine on top of your list.

The "contra" list which follows now, gets shorter with each newer version.

Contra: Though it does have tube curves, they are not displayed the normal way. Theoretically this may be no issue, but when you want to show the tube curves to somebody else, or compare them to data sheet curves, you have a problem.

Pro: Hardware made by a company who uses it in their own production too. It has many great features.

Contra: Very few tube sockets. Take good note, for power tubes and small signal tubes, you need to buy another tester. Alladin1 is for power tubes and Alladin2 for small signal tubes.

Yet Alladin2, basic version costs less than AT1000.

Pro: The good hardware, the stand alone function, and rugged case. You can take this tester along with you for service.

Contra: Software full of bugs and errors, and no updates.

This is a new product. Final information follows.

Pro: Price-Performance Ratio is fantastic. Very good hardware, mature product. Easy to build, and needs not much time.

Contra: A very small one. RS232 ports, your PC may not have that. So this adds to the costs, and also installing uncertified, mostly Chinese RS232 cards, is getting harder with each newer version of Windows.

Note: The uTracer works perfectly with a RS232 to USB converter cable. Users have replaced the MAX232 RS232 driver with a simple Bluetooth module and operate the uTracer wireless.
