37-630 sub-chassis removal...?
#1

Hi all- just joined, looking forward to the sharing of enthusiasm and knowledge here! I'm fairly new to this whole thing, having had zero interest in electricity/electronics for 68 years and then I saw "Electronics for Dummies" in our library and now I'm all-in, trying to learn what I can from books, forums, FB groups, and finding and restoring old radios. I have about 1/2-dozen restos under my belt, but recently picked up a project that's quite a bit more complex: I need to remove the sub-chassis in this 37-630 console so I can get access to component replacements, and to replace the rotten rubber grommets holding the tuning condenser in place. I'm very reluctant to just start disconnecting wires and un-bolting things with zero prior experience in this kind of electro-surgery; can anyone here point me to a step-by-step tutorial, or any other reassuring process that I can slowly follow?

Welcome Oldcoot! Start by getting a very clear schematic, and thoroughly read it until you have a working idea of the project at hand. Second, take numerous photos of the chassis, paying attention to wiring paths for re-installation. Third, mark everything when possible, and be ready to replace a lot of wire with decayed insulation. Best of luck! Take care and BE HEALTHY! Gary

This web page helped me when I worked on a 37-630 table radio. It’s not a step by step but it has some good info.

Thank you, Tucker- that does indeed help! Hard to believe no wires need de-soldering/cutting! Guess we'll see about that.

Thanks Gary, will do. I also stumbled upon a thread/blog by Ron Ramirez which is exactly the kind of tutorial I was hoping existed somewhere on the Web. Getting grommets that I hope are right from RenovatedRadios, so I'll methodically forge ahead on this advanced-level (for me) deconstruction.
