Re: External Amp

Richie Chambless

I have the same amp on my Bitx. I’ve gone through several IRF530s. I did find a suggestion to fix this issue. I found an article that said to put a 22 ohm one-watt resistor across output of the first transformer (gates of the finals). This is said to help with instability. I am also going to install a 50 ohm pad as suggested by Allison. My goal is to get to a stable 35-40 Watts out.
