Thanks Chris,

I was searching for a simple and easy neutralization method that doesn't require cabinet opening and wires desoldering.

I'm restoring an old Yaesu FL-200B transmitter with 2 x 6JS6C in the final PA and the -80V available for grid Bias suggested to me the neutralization method I explained in my first message.

Thanks and 73

Not sure but maybe this weblink may help?

Section on adjusting methods.  I believe I used the third method to neutralize a Swan 400 PA stage.  But it has been a while since I did it.
