Hello I just got a modified Elisra 20W SSPA for 3cm. I am told that it 
is 9V for the Ud and -5V bias and that it is very important to 
ensurethat the -5V bias is always present before the 9V supply is 
applied. Did anyone ever make a PCB for this application? I know that 
there were a few of these amplifiers around in the past.

Any info or advice?

Regards

Conrad PA5Y
