I just received Ken's 45/2a3 amp. I am using it for my compression driver horns from 800Hz up. I was using a 'quite famous' UK brand 300b amp. On replacing the 300b with the 45 Otomon amp, the improvements were immediate (after 30 mins warm up) and evident. Voices and instruments took on a clearer outline and there was more separation. Not only that, the rhythm and timing improved and instruments stopped on a dime (if they were meant to); bongos had more of a tone (havent tried other instrumentals) and also backgrounds seem darker. I am enjoying the music so much. Overall its a great amp for the money - - and all this including using very affordable tubes (used) that I purchased from ebay - Ken, thank you !

His work is very beautiful and the amps look very cool. I am interested in trying one, a SE with maybe an 808, 2A3 or 211 but just about everything I see is 100V. I won't use a transformer because they all sound so bad to defeats the purpose of the simple clean amp circuit. Are there 120V SE amps I'm missing? I think he has one for sale now but it's PP. Thanks much.Ian |
I ordered this amp to Otomon Lab and really happy with its sound.You can see the perfect wiring inside the amp. Output is about 15W but it is dead quite from my 100db speaker. Killer sound, much better than my Yamamoto 300B tube amp. I dont know because of 300B tube is not as good as 808 or Ken-san 's technical. Ken-san is very nice, he explain and give suggestion to any thing related to technical. Here is my amplifier > http://soundgate.net/products/detail.php?product_id=ODY5 |
I just received a custom built 300B amp from Ken. Ken is very responsive and answer all my question within a day. His amp looks as beautiful as it sound. The wiring is super clean. I think it needs more time to be broken-in, but it sounds good right out of the box. My only challenge in the process is to choose what amp to be order. On his web site, there is a huge variety of previous built amps, and price range from $1000 to $8000. Now, I am tempted to try another amp from him, that is the problem! |
