| Thank you both, put in higher value Electrolytic Caps and it reduced the hum a lot. Still have it though but it isn't bad enough to worry about. I think when you put the case on it it amplifies the sound and brings out the hum more accoustics maybe. I believe there is a bad resistor that is changing value when it heats up. The volume changes from good volume to lower volume then it comes back up to normal after 5 or so minutes and plays fine after that. Already changed the tubes out and they didn't make a difference. Maybe after I get it to stablize I'll loose the hum all together. One can only hope. Thanks, George T |
