Hi,

Just looking for some advice here.

My Grid meter setting on my SB-200.

Goes negative with the tune control fully CCW.

When I turn it starts to rise until it is at peak power out.

I did miswire C3. It did fry. reversed the polarity when I put it in.


that is a filtering cap for the relay antenna line.
Thoughts?
Problem.

I am not putting my nice new tubes into an amp with a fault.
