I dug through the service info and see that they did use 12BP4, 12LP4 and 12TP4 with the 20B1 chassis.

I think Karma Kiri may be right. It might be a 12QP4. The factory rubber stamp warns against using other tubes. The big difference is the second anode, which has the Dumont type connector to a pin sticking out no tube. There is also no capacitance grounding.

Here are some things that are different about this set.
Push -Pull audio output 6V6 tubes in power supply. AM-FM radio chassis. Deluxe two speed changer.... This must be a nice set when finished. Bill Cahill
