These were from a VAIC Dealer, who never sold them. I bought them from this dealer personally after the VAIC brand was obsoleted. They were only used for demo purposes, in a special test room in his private house. They have almost no hours on them, they are shiny like new, and were never transported to HiFi shows, or anything like this. I picked them up myself by car, so they were not even yet shipped by carrier even once. The original wooden shipment crates are unused.

So call it NOS amplifiers. Can be shipped wordlwide quickly. We just need to give those a check up. Will be sold by JAC Music, with NEW EML 520B tubes, and full guarantee on everything.

These are the reference models.. and hey... that's what they are. If you look inside, it makes your heart beat faster. All triode amplifiers, no feedback. Gold plated hardware, even the switch at the back for the bias control is gold plated. It has symmetrical and unsymmetrical inputs, you can hand-adjust the bias yourself, with a precision build-in digital reading. After adjustment, the digital meters can be switched off, if you don't like the red- letters of it, in the dark. So you'll see the tube glow only. The amps has tube rectification, 6SN7 pre.amp tube, and a beautiful directly heated driver tube AV8B, and two 520B output tubes in Parallel Single Enden for each monoblock. The deck and transformers are Rhodium plated. (This looks like Chrome, but has a more blue-grey color, it looks more modest like chrome plated). Wooden side panels are thick piano laquered, in black.

Note, that this amp allows you to do a tube change yourself, check the status of 520B tubes yourself, and re-adjust them yourself. You don't need to ship it to a dealer for that. It may not seem important now, but it will be after some years, and it's a MAJOR advantage of this amplifier over the lower class VAIC models.

This is the BEST and largest VAIC amplifier EVER MADE
