RE: Serious Micro-Phonics and Hum from Citation V

Jim!
man hate to drag you into this, yes the micro phonic sound will transmit through both channels, the hum is a tad higher in one channel than the other.I am suspicious about it being a tube issue. The tubes I am using are the new ones you sent..
and yes this is the same amp that Samra and I fixed the trafo on.
I can check the heater voltages on the 12by's tonight..
thanks,
Jeff
