I just ran the amp for 20 minutes with the preamp out and the shorting plugs in. It never made a peep. I am going to go back and try taking out the bypass cap on the 6n7 and put the preamp back in and see what happens. Oh, one other thing; it got real quiet in the house for a short while and I noticed that the potted power tranny has a pretty good hum to it when full mains is applied. Is that anything to worry about? I have never heard a potted power tranny hum before.
Thanks!
Vince
