Good morning Grover. I have today and Friday off due to the holidays, so I am taking vacation leave for the rest of the week to try and get some remodeling done around the house.
I tried the grid stopper just a short while ago. I put a 1k resistor to pin 4 of the 6n7 and attached the input wire to the other end. I kept the end on the relay short by doubling over the lead and sliping it under the clamp. Pins 4 & 5 are tied together with a short lead. They don't need separate resistors do they? I left the bypass cap for the cathode resistor of the 6n7 out, but the preamp was in.
Well, it went about 12 minutes this time before it went pop and stopped playing. Does this mean we are making progress? What do you think I should try next?
What was your take on the output cap of the preamp and the specs of the PS tranny?
Thanks!
Vince
