I picked up a Raytheon RR-30 broadcast remote mixer at a swap meet; it was cheap, and I couldn't resist! Does anyone have a manual or schematic for this thing? It has been modified severely, and I would like to restore the original circuit. Radio Museum has pictures, but no data. Tubes are two 6J7, two 6SN7, and a 6X5 in the separate power supply.

This oldie certainly worth to be restored. Remember it needs an external power supply unit which is very often missing, but easy to duplicate. I have the complete manual... somewhere. (need to find it).
In the meantime, here's the schematic of the main mixer unit:

Nice find. Do the 6J7s have shields over the top caps?

Yes, they do. I will put up some pictures when I get the chance.
