I want to thank the forum, has taught me how to restore my Philco 80 jr.
I replaced a capacitor (not original) for Mershon covers the coils and the valve 36 be replaced by corroded by rust. Boat filled capacitors, filter capacitors with new electrolyte inside, new wiring, new potentiometer, ........

In the original state of the radio was the cable that makes the modification for amplification from the 1st valve to the central terminal of the volume. When reassembling the new wiring I've respected.
I note that the reception is very low and decided to check the wiring. I find that the connection is made in the second coil (No.1 picture) when it should be on point number two.
Should I change the connection?, Or the result will be the same?.

Did a nice job.
Someone here can probably tell you an answer to your question. I'm not sure myself. Maybe post the schematic.

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!!
Terry

Thank you very much everyone.
Restoring the've been able to make thanks to the forum, directly or by following the links recommended.
The cable that originally had (Photography) was connected properly, allowing for the "trick" of amplification.
To tune in stations I connect a TV antenna amplifier. I want to try a small amplifier antenna, used in vehicles.
A greeting.
José
