[Amps] Cold neutralization with high voltage bias?

[Guido Tedeschi]

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
