I'm reviewing the schematic of the Princeton 6G2 (attached). In looking at the layout (pg 2), would heater wires connect the tubes? I'm new to this as most videos I've watched and layouts I've seen with other amps illustrate twisted filament wires to connect the tubes. I appreciate any assistance in advance.

Long time ago when that amp was new, it was common to connect one of the power transformer filament leads to chassis. Then the other filament lead would connect to a tube socket and a single wire would connect from that tube socket to the next socket, etc. This means that the other filament pin of each tube socket would be connected directly to chassis.
That method of filament wiring was abandoned in favor of an improved method that ran two twisted wires to each socket. Same as the method you used on your 6V6 Plexi 18 project.
BTW, did you ever get that 6V6 Plexi 18 working?

Thank you for clarifying. Based on the background you provided and the diagram, would the green PT line going to the pilot light connect there and then to the 6V6GT pin 2, and then connect pin 2 to the next 6V6 pin 2?
BTW, I did not get the other amp going. I think I blew the PT. I did have a forum member offer assistance I just have not reached out to him.

yes
