The output section alone has 1st AF, 2 drivers, inverter, 2 outputs for a total of 6 tubes just for the audio section. Gives you an idea. Nice radio though, I'd collect it in a heartbeat! Make friends with the poly unless you want to strip it. I doubt sanding is a good idea because the doof who poly'd it probably sanded it and the veneer is running thin.
