Thank you for accepting me into the group. I hope I'm on the correct thread to ask my question. This is my first restoration of a Philco 60B (1933). I'm smart enough to know when to ask someone more knowledgeable than I, so here goes: I have taken two, Philco 60B chassis and combined them into one radio. Both radios were BADLY abused i.e. grill cloth and speaker cone ripped out, mica trimmer caps missing, antenna coil and 1st IF missing, chassis left outside in bad weather, etc. - You get the idea. I was able to harvest enough parts to make one complete set. I re-stuffed the condenser blocks, replaced out of tolerance resistors, re-wound the oscillator transformer primary, and replaced decrepit wiring. All IF's and the antenna transformer show continuity. The tuning condenser was so badly rusted and filled with debris, that it had to be soaked, overnight, in vinegar to clean it up. (Yes, I removed the mica trimmer caps first.) As of yet, I do not have a dial, or the 1/4 inch plastic alignment tool - both have been ordered. I can inject various modulated RF signals at the antenna post, and by rotating the tuning condenser, I can hear the tone in the speaker. However, I am not able to tune in stations - I just get LOUD static in places that seems to indicate the presence of a station. Does the fact that I can hear different modulated RF frequencies indicate that everything is in working order, and I just need to do an alignment? It will be another month before I receive the dial and alignment tool, and I don't want to waste time, if I should be looking for another problem. On a side note: It's been over 30 years since I've done work like this. I never was fantastic, but I could usually get a set to work. I'm hoping by reading/studying/and following this forum I can become more proficient. Thanks in advance for any/all responses.
