Title: P/P plate driven issue
Post by: Colas LeGrippa on March 24, 2013, 12:43:53 pm

Hi, I have built a Marshall 2204 master volume amplifier and I skipped the tone stack, feeding the PI right from the first half of the cathode follower tube plate.
I think I missed something because the overall volume is weak. without life.

Thanks

Colas

Get some RG-316 for your shielded cable needs. Probably never have that problem again, especially if it was because of a melted center conductor insulation.
