Bill,
Since the 520S is a tube output transceiver, I think you need to tune
the PA stage into a 50 ohm dummy load so it matches the input of the KPA500.
Yes, then start at low power and bring it up until you have your desired
power out of the KPA500.

I want to use a Kenwood 520S with my KPA500 amp. I have the cable from the 520
Remote connector to amp PTT IN.
I assume I should tune up radio with dummy load and then turn Drive down low
and switch amp to Operate. Now turn up drive to get desire amp output.
Now I ask, “What have I forgotten (or never knew about tube radios))?”
Anything else I need to pay attention to or what am I missing?
