Hello again,
As I stated in my last thread I am in the process of rebuilding an Eico HF-81 amplifier. I got rid of the very loud hum I reported in the first thread by discovering that in the process of replacing the power supply filter caps I had bent a resistor lead and it was touching one of the tube pins!!! The amp sounds real good now but I have a very mild hum in one speaker and a slight hissing type noise in the other speaker. Any suggestions as to the source of this noise would be greatly appreciated.
Thank you all for your help,
Jim
