RE: Electronic Transformer heating for the gm70 test

For anyone who cares :)

I have done some more testing I wanted to see what the output on the amplifier looks like as far as hum well there is hum allright 400mv of 37kc hum!!!!!!!!!!! WTF??

IMO totally unacceptable and if i would have known about this before hand I would have NEVER even tried this idea

even though I could hardly detect this hum except for the unit itself does make hi freq (37kc) noise that drives me crazy, so when I seen this it is a deal breaker for me IMO this is not HIFI this is LowFi

Thank the good Lord that we have something that IS HIFI! Rod Coleman Regulators

what to do with these now LOL
