RE: Negative bias supply problems

Posted by TomWh on June 26, 2017 at 08:32:39:
If my understanding of fixed bias is correct there is no real Current going thru it. You said you do not have the interstage in the circuit did you ground the output side? That could pull some current and drop some real voltage.

All my hookups with interstages the secondary is tied to the grid of the tube. That stops any real Current from flowing through the circuit.

If you are getting the right voltage range from the fixed bias circuit I can not see how connecting a dead end street could change that. If I am barking up the wrong tree there are plenty of circuit guys on this forum who will chime in.
