    What do the Japanese know about tube audio, that we Americans don't ??  Nothing. 

     

    That guy, who I have never even heard of, does not know the most rudimentary things, on how to lay out an amplifier properly. 

     

    The Power Transformer and the rectifier tubes have to go as far away as possible, from the amp's sensitive input signal tubes. 

     

    Putting a rectifier between two input tubes, is absolutely a novice's total stupidity showing...no thought , he likely didn't know better.   It is the worst place possible to position a rectifier tube.   Now YOU know this also.  Welcome to the club.

    You know what? I'm starting to agree with the other guys here.

    I'll just disregard your posts.

    Besides the zip ties, the Manufacturer positioned the rectifier tube, right between both input tubes

     

    Think about it for a moment.  The rectifier tube has the nastiest of fields associated with that function.  Of course, everyone caught that - right away,...... except for the Manufacturer.  

     

    Those neatly spaced tie wraps and red and white wiring will sell amps, if you are impressed with that.  Those electrolytic caps are

    nice also.   See that 6 Watt 18 Ohms power resistor between the rectifier tube, Pin 8,  and the choke?  Sure, go ahead and add some series resistance to the Finals stage, it doesn't matter at all. 

     

    Its all very nice !  Glad to have seen it.  Is it three grand, or four, or five or six?  I'll take it out of my 401K.  Red and white wires, wow, and blue to sell to us, in the USA.  Will this piece get me that " tube sound "  that everyone talks about in audio ???

    Well, that guy, Tossie, published over 200 projects http://tomo.fine.to/V.World/gallery.html

     

    He was quite known in Japan until he passed away in 2007. 

     

    Have you built 200 or more amps? 

  3. Very nice Williamson circuit (or close to one). The output tansformer seems identical to that of the Radio Craftsman C-500 amplifier.

     

     I have bought 3 pairs of these with my best friend. but never had a chance to listen to them as he had suddenly passed away. He only finished restoring one pair and claimed the they easily rival his MC-30s. 

     

    I already left the US and went back to Israel due to family reasons and the amps and rest of his gear were sold by his widow 😕..

     

    Interelectronics was a small NY based company aimed to compete with Marantz. Rumor has it that later it changed its business direction to become Intel...

    Brociner was an early distributer in NYC and became the first blatant infringer of the patent.  Besides Vitavox and EV, other licensees included Radio Shack and Dominion (Canada).

     

    and Lowther too with the TP-1. I actually own a pair.
