I got two Zenith sets at an estate sale today for $20 each. I kind of wish I'd left the 7S633, because not only is it really beat up, but Zenith really cheaped out by 1942. I'd at least like to get my money back as I have no interest in repairing it. The 10S464 however, is in much better condition. I'm taking it to the radio club tomorrow in hopes of getting it to at least make more than a 60Hz hum. It's missing the station preset assembly. Could this keep it from playing? When I was moving the radio out of the sale, it was extremely crowded, dark, and loud. The preset assembly fell out of the radio and just then, somebody asked me if I needed help. I instantly forgot about the assembly until I got home.

Good news and bad news. I went back to the sale early this morning and got the preset selector. Thankfully, the guy running the sale saved it and set it aside. Bad news - we think that there is insufficient voltage on the plate(s) of the 6V6('s). They are running lukewarm with a filament, but that's all. I replaced the electrolytics, and that got rid of the 60 hz hum, but now there is just a small hum, but no audio. I didn't get a chance to check voltages this morning.
