I had a look but couldn't see how you could do that. CW yes but couldn't
figure it out for SSB. Did you read it in the manual?

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?
