Default Re: EL34 power amp reworked as a stereo amplifier

Nice work old chap, see you got your toroid cover, guess you changed your mind about using a saucepan. good to see it finished mate.

Re the 50hz hum, pull the EF86, is it still there? Are all heater's referenced to ground? did you connect the EF86 screen? That's all i can think of for now apart from if those suggestions don't change anything pull all the valves, power up and see what you hear.

Tother Andy.
