The P-P 6V6 are obvious. I have a Motorola stereophonic amp chassis from 1961, there are three or four 6BQ5 (bass channel is PP?) IIRC.
Im looking forward to hearing how yours sounds.

I have the same amp, but mine was built in late 1959. Mine uses four 6BQ5's, two in push-pull for the bass channel and one each, single ended for the left and right channel.
The amp, pictured was built in November, 1963. It's stamped 11M63 on the back. Probably the last of the larger tube amps from Motorola. Everything newer seemed to be solid state.
