Like I said. This is the filament. All wires for the filaments in all the tubes, except the rectifier one, are parallelled. So you will have two sets of wires going between the tubes, or one going between them and then the other going to chassis point. Whichever way they chose to connect them.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
