Hi Gary,
I figured on replacing all the electrolytics and paper/wax caps. I noted one cap was actually leaking at some point and another has a slight bulge in the can. I usually check the resistors to make sure they are still in tolerance. I pretty much always end up replacing some. I couldn't help myself! Removed the chassis from the cabinet. There's going to be a fair amount of work cleaning it up, more than I thought. The rubber insulated wires that come from the stepper relay to the station lamps will need replacing, they are all broken with bare wire showing. I have a YouTube video saved that does a good job of showing how to rebuild those lamp sockets. The rubber on mine appears to be fairly flexible so I might be able to save that part. There is one odd bulb that is labeled Philco 44 6-8V. It is frosted and has a black dot painted over the end. It has a grounded holder but it was not inserted anywhere. I really, really, really, don't want to, but I think I'm going to have to remove the tuning cap to clean it. If anyone has some pointers on cleaning it, let me know. I peeked underneath the chassis and there is still a fair amount of cloth covered wire, but also some rubber insulated wire that will need replacing. I will have to check the transformers to make sure they all have cloth covered wire. I've attached a couple of pictures of the top. Tubes and shields have already been removed.
I was really amazed when I removed the cover to the stepper relay, I found it was foam insulated! Even back in 1938 they wanted quiet!
Thanks,
Rich
