Popping The Top On The Orpheum

8 03 2009

Time now to crack open the back of the Orpheum and see what lurks behind the 50 year old thin plywood.

Three preamp valves guard the approaches to the tube bank; one Sovtek 7025, one blank ECC83 and one totally blank 12AX7.

The output tubes are a pair of RCA 6V6GT valves and the rectifier is a RCA 5Y3GT. All the RCA tubes are marked “Radiotron Electron Tube”.
