I am working on an Aetna tombstone radio, and I am having some problems, mainly squealing noises. It is obvious that alot of components have been quickly replaced, so I need to find a schematic so I can check numbers--none are available here. Does anyone have one that can be purchased or does anyone know from whom I can purchase a schematic? Any help with this would be appreciated. Thanks, Nick Tillich

Aetna is under Walgreen in Rider but I didn't find your model number. You may try looking at other Walgreen schematics here on nostalgiaair.

Squealing is caused by feedback. It's important for tubes to be shielded and bypass caps to be in place. Be sure electrolytic filter caps have been replaced.
