According to the manual which is easily located online, the transmitter power is
adjustable.
If it wasn't, a 6dB pad would do wonders.

I might be way off here but from what I recall these older vacuum tube final
amplifier radios have output that is variable in fixed carrier modes such as
CW but which almost always produce full output in SSB. You might be able to
reduce output by winding back the mic gain but it will likely sound a bit
"thin" and any loud noises over an above nominal speech will produce more
output. When you set the carrier or drive control that only has an effect on
the CW output, it doesn't set the SSB output.
I recall a common way to limit the output of these radios in SSB mode was to
feed a dc voltage into the external ALC input of the rig in order to have it
reduce power.

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?
