The research bench

Old radios.
New ways to find answers.

Follow the trail from a model number to service literature, schematics and documented parts. AI searches the web and brings the sources back to your bench.

What are you working on?

A make, model and chassis number make a better starting point.

A research assistant, not a repair sign-off

AI can miss a revision or misread a value. Verify every component against the original service sheet and your actual chassis before ordering or replacing parts. Vintage radios can retain lethal voltages even unplugged. Hazardous servicing belongs with a qualified technician.
