RE: Help With Futterman Mono Amps

Posted by lucisfero1 on December 29, 2016 at 00:02:33:









I just came across this posting and I can confirm the H-3a use the 4 per channel 6KG6A/EL509 and have the 3 large caps. Julius delivered my amp after he repaired it and we listened to some music ( KLH Model Nines).
Some of the H-3a chassis used the H3 chassis which had on the front left, TECH Instruments Corporation and on the right front, stereo/mono OTL power amplifier. I've had this particular OTL since 1972 and its still powering the Nines. People who say the Futterman is unreliable maybe had bad luck or abused the unit. I also think the Model Nines still stand up to anything made today, the pairing is beautiful and engaging sonically.
