I guess the question to ask is, on Uncle Joe's
1970 color Philco, is the volume located in the
input stage, or the power amp side?

It's an attenuator between the FM discriminator tube and the power amp tube.

Same for the volume on a stereo receiver in
the home.

It's between the line preamp stage and the power amp stage.
