Otomon Labs. Soundgate Japan

most of the recent issues seem to be related to the 1940’s Western wiring, which is very difficult to solder. but one can always opt for regular wiring.

allow me to add that the sound that KEN achieves is incredible. we recently did an A/B of this custom 71A amp...

...against an American custom amp twice its price, and KEN’s was drastically better in every way. it was also equal on low levels to a TAKATSUKI based 300b with all-TANGO iron, which is a prototype that will cost 7-8K when complete.

I just bought a 45/2A3 amp from Otomon Lab. This is the best amp I ever have. I don’t think I need another amp for my Lowther based horns. Ken Uesugi is a master builder of tube amps. This amp he built for me sounds much better than my previous Yamamoto A-08S (a 45 amp). It’s about the truth and spirit of music.

This is the amp I bought:

Ken is very cool. He just made a 45/2A3 convertible amp for me.
i have at least 50 years of experience with Hi-Fi and this is the sound 
I’ve been searching for. Only caveat: you must have speakers that are 96 to
97 dB efficiency. Otherwise, the amp just can’t give it’s all (and that can get plenty loud with lots of body). I will never part with this amp.

are you using a pre? 

I stumbled on their website a few months ago and they are the real deal but you can get the same level of craftsmanship or even better with Triode Lab of Canada.

Don't think you can go wrong with either as 2A3/45 is where the magic starts 🎶
