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

This is a KIT, but you get supplied the working PCB, 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.
With my own build interface on it. Under construction. Not for sale here
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.
This is a new product. Final information follows.
Price on Ronald's homepage, 250€ by Paypal. This includes all parts for the PCB + Software. You must buy yourself: A old Dell Notebook power supply , a case, and tube sockets.
Ebay prices from 250...400 Euro. Add the Agilent 20 Channel multi meter 34970 A with interface card. On Ebay for appr 500 Euro. This basically works. A PC Interface card for the 34970A costs appr 100 Euro.
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

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. President Audiomatica Srl

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.

This is a new product. Final information follows.

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.

22 Bits when I use Agilent 34970A.
Measurement range Anode
Absolutely AMAZING. It can do 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

This is a new product. Final information follows.

0..400 V @ 200 mA

0..250V @ 100mA

300V at lower current

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.
This is a new product. Final information follows.

0..50V

This is not enough for large triodes like 300B

0-15V 0-150V
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.
Yes. Miracoulous engineering. It has a tube electronic nano-Ampere meter, which can be calibrated with internal reference before testing. Best I know.

HARDWARE
 
Shorts test
No. This is dangerous. one day you plug in a shorted tubes, or you connect something wrong.
Yes
We have to say it as it is, the teser has no shorts test. However the manufactirer says, when you use the Canor burn in equipment, any failures will be found before.
Yes
This is a new product. Final information follows.
No. This is dangerous. one day you plug in a shorted tubes, or you connect something wrong.
Any short test, it can be done. Even has an electronic nano ampere mater for this.
Gas test
No, See above, because a gassy tube tends to short violently at higher voltage.

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 hardware.

The Fan is definitely MUCH too loud. It is really a pleasure when you can switch the machine off.

This is a new product. Final information follows.
Very good
Absolutely superb
SOFTWARE
 
Software updates
No. Version 2.1 for DOS is available from the Audiomatica Website, but this is not an update, it is very old. Software is fully mature, does not need an update.

You download the software for free.

Software is not compatible with very old models.

Updates. What updates? To my opinion the software is a sad collection of misstakes and errorz.
This is a new product. Final information follows.

Yes regularly, download for free

Curve tracing
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.

Optics of the curves not as nice as the SOFIA. It has the "Excel Look" like Amplitrex has, but options and possibilities are the best of the best.

What is missing is the classical curves as you see in any datasheet. Yet is measures very interesting, and professional.

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.

I am not enthusiastic about this. Also the "Excel look" of the curves is not nice.

This is a new product. Final information follows.
Curve charts are drawn the way they are supposed to look, and great care was given, to make give curves look original shape and functionality as in old datasheets. The others can take this as an example. A nice improvement would be a way to plot them as vintage "datasheet" look alike curves.
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.

This is a new product. Final information follows.

Speed was traded for low complexity and a low price, so 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.
This is a new product. Final information follows.

Yes, traced curves can be stored and examined later with a cursor

Tube parameters at multiple operating point

Wow! A most remarkable feature is used here. 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.

Software Maintenance

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.


This is living software, suggestions and improvements are implemented in the next versions. A perfect attitude! Very old hardware can not run all newer software versions, so you need to check that when buying an older version.

I reported many issues and small items. My impression is, Amplitrex is not interested in improvements whatsoever. Don't think I never tried.

This is a new product. Final information follows.

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

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.
This is a new product. Final information follows.

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.

This is a new product. Final information follows.

Yes

Software (3)

Grid voltage

for DHT tubes

is displayed in "AC" mode?

Grid voltage is measured wrong for Directly Heated Tubes. The effective grid voltage the tube sees, in increased by half of the filament voltage. This was not compensated in the software. (Though this would have been very easy to do).

So when the tester draws a -1Volt line for a 300B, it is in reality the -3,5 Volt line. Same error is made with the normal"Tube Test" page it produces. With the Sofia, thinking of an improvement is 20 years too late of course.

Yes

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

 

I don't know.

So when the tester draws a -1Volt line for a 300B, it is in reality the -3,5 Volt line. Same error is made with the normal "Tube Test" page it produces. With the Amplitrex, I only report it here, for everbodies interest, but reporting it to Amplitrex has only resulted in a work-around advise.

This is a new product. Final information follows.
I don't know.

Software (4)

Transconductance

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.

This is a new product. Final information follows.

Sets of transconductance curves can be directly extracted from the measured anode currents.

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.
You can simulate it with self made cards easily, but you do need to understand how this is done, and also you need to know yourself how to make cards. This is not presented on a silver platter for free in the internet.
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.
No
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

I think when you are very good, you might add it, with some method to bypass the bandwidth filter for Gm. The difference between filtered and unfiltered is the added noise, which is composite distortion. Not extremely hard to do actually.
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 so it can only run under REAL DOS, and not under a DOS virtual machine, like the ones that were included for free in all windows versions lower than W7.

* However with DOS BOX Megabuild, it seems to work with a well done 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. Highly professional software, with original and normal looking tube curves, ready to put in a datasheet (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: Very good hardware, low price, and very 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.

No intention to compare with the others. Regard it my personal project. I want to use it later for special tests, that I can program my own way, and simply do things the way I want.
