Default Collins 30L-1 Output drops at higher bands

Thank you for the advice. I did check the -170 bias source and it is -166.5 V DC with 5.5 volts ac ripple. So I'll be replacing the rectifier with a modern one.

You could put 1N4007 in there and it wouldn't hurt anything and might improve
long-term reliability. But I'd first replace that 10uF capacitor, which you
already know is bad and is most likely the source of that ripple.
