Hi Pillo 69
A belated welcome to you. The volume control on your model 80 isn't really a volume control. It does not connect to the audio stages, in your case the 42 tube. It connects to the antenna and regulates the amount radio frequency (RF) signal that goes into the mixer tube. The audio stage is set to operate max volume all the time. I would rewire it
to agree with the schematic. On some of these sets there is a gimmick capacitor (2 wires twisted together but NOT connected electrically) Repocate that also for best performance.
Nice job on the set!!
