In Reply to: RE: Is there a secret to using the 7A4? posted by Tre' on January 7, 2017 at 11:20:06:
Thank you for the help. I ran across a wiring mistake. Since, i am using fixed bias, which i hardly do i wired the grid to ground resistor to ground forgetting that the fixed bias circuit establishes the ground. But i will try your suggestion as the 7a4 plate voltage is too low. Btw, is it better to have bigger plate resistor (80k) or smaller cathode resistor of 360R?
