The 20X122 with a single chassis is the earlier model, but maybe they already had plans to switch to a lower chassis
Bummer. I'd love to see some pictures of the massive bakelite press that made these huge cabinets
The 30B1 PS and audio amp are overkill for this set as they were meant to power larger speakers and AM/FM/Phono. So I might have to do some tinkering with that speaker.
I think I had the original 30B1 speaker years ago, but lost it somewhere along the way.
