There was also a version of this console that contained an AM/FM radio.
Oops, I made an assumption there were no more tubes than the photo shows.
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.
