REAL TVs have TUBES!

I think there are a couple of wires swapped for the Predicta tubes, to prevent the filaments from coming on if somebody puts a 2.7 volt tube in a 6.3 volt TV, or from installing a 6.3 volt tube in a Predicta. If you don't have the right socket, you can check the schematics of the Predicta and any other TV with that size socket but standard filaments, and temporarily swap the wires.
