Friends,
I've got this amp I built using an old Hammond organ amp. It has 6sc7 for preamp and PI tube. It works fine but if I plug in my tuner with the input jack plugged in to the power supply while the amp is on, the amp cuts out completely. I then wait a short while and it starts working like nothing happened. If I turn the amp on and then turn the tuner on,(with everything plugged in before I throw any switches) no problems. Any idea what would cause this sort of thing. I'm using an Ispot power supply to the tuner.
