From looking at the components I can see a stack of diodes and a bridge rectifier on a single finned stick.
These will be for grid bias and HT.
Without a reverse engineered circuit diagram I can only guess that the stripy item is a prehistoric capacitor rated in jars.
I would not expect there to be another jumper. The existing one needs to be moved around to get various voltages from the four pins.
