So dad frequents the rose bowl swapmeet among other things, and he has picked up a few radios for me, some of which i have yet to unbox and go through....but he saw this and coudnt pass it up as he wants to teach me some of the woodworking/resto skills he has which im pretty stoked about. But i wanted to get some info for this bad boy, see if anyone had a schematic

Its a RCA 16T3. The cabinet is absolutely gorgeous, and needs very very little work...only 2 or 3 nicks, and the obvious on/off swith someone added in the upper left corner, prolly cause of the original switch failing. It too has ben replaced with a regular pot, and the knob is MIA. So i need to find a knob, and figure out if the original style switch is available, or if i can just use a nothing special on/off/volume control....problem is finding the proper knob and shaft size...Also has a TV input, so im guessing early maybe mid 50's?

So ya, thoughts, comments? im have this posted in tube stuffs at audiokarma too :p

That's a 1941 model, RCA began installing TV inputs on their higher end radios in the late 30's to accomodate their TT-5 television recievers, which were video only and required being connected to a radio to recieve TV audio.

Send a PM to Mike Koste of Gobs of Knobs. He's on this forum: his handle is ekimetsok. Refer him to this thread for the picture: he'll have the missing knob.

Check the Nostalgiaair site for the schematic. They will probably have it available as a free download.

Here's the schematic. Click on the "eyeball" to open.

The radio takes a special tapped volume control/power switch which is a tone compensator, boosts bass at lower volume. Playthings of the Past might have such a control, or Mark Oppat of Old Radio Parts. If you can't find one, you can just ignore the tap and the control will work like an ordinary one. RCA made a number of similar 6 or 8 tube sets around this time: they are good performers.
