Hi Everyone,
I am in the process of restoring a Philco 37-670 console floor model. So far I have replaced all three filter capacitors, two of the Bakelite blocks (including the one containing the across-the-line caps) and the pilot light and the shadow meter light. Last week, I powered the radio on for the first time so I could get a baseline on its functioning before continuing with re-capping, etc.
The radio powers on just fine - it runs at about 90 watts on 110 volts and all of the tubes light up. However, there is no reception of stations whatsoever and the volume is very low.
My question is why this radio is not picking up stations. According to the instructions on the schematic, "if a temporary aerial is used, the jumper should be across terminals 2 and 3. The aerial connects to terminal 1 and the ground lead to terminal 3." So I placed the jumper across terminals 2 and 3 and I attached a long piece of wire onto terminal 1. I think this should be sufficient to pick up a rather strong AM station located about 2 air miles from me - that station is so strong I can pick it up on even the most deaf radios. Other tube radios in my collection have received this station even without an antenna attached. But the Philco won't even receive this station.
Any ideas as to why it's not receiving anything? Unfortunately, I don't have a tube tester so I don't know how good the RF tubes are in this set, but they do at least light up. The set did come with some kind of antenna attached to the cabinet - it's kind of compact and inside a metal case. I can't quite figure out how that antenna is supposed to work. But right now, the cabinet is being restored by a family member so I don't have ready-access to it.
Thanks in advance for your help and advice!!!
