Each amplifier uses four 6L6G, two 5U4G, one 6SL7GT, one OC3 and one OD3. Included are all original RCA tubes which all test very strong.
Each amplifier has a Langevin power tra...nsformer (Part No. L2324) a UTC output transformer (Part No. N6569) and a UTC input transformer (Part No. 6567)
Both amps are in beautiful original condition and very clean! They are complete with all tubes, rack mount flanges and front cover panels.
Tubes were tested on Dan Nelson calibrated TV-7 tester as follows:
The 6L6G tubes are all RCA with the same internal structures and silver printing on bases. They test 38, 38, 38, 38, 38, 38, 36, 36 with 25 being the recommended minimum.
The 5U4G tubes are all RCA with silver printing on bases and the same internal structures. They test 56-56, 56-54, 56-54, 56-54 with 40-40 being the recommended minimum.
The 6SL7GT tubes are both RCA with silver printing on base, smoked glass and identical internal structures. They test 46-48, 44-46 with 32-32 being the recommended minimum.
The OC3 tubes are both RCA with silver printing on bases, identical internal structures. They test 104, 104 with 40 being the recommended minimum.
The OD3 tubes are both RCA with silver printing on bases, identical internal structures. They test 83, 82 with 40 being the recommended minimum.
Please note that recommended minimum is considered to be about 60% of what the tube should test if new, so these are very strong tubes!
Amplifiers themselves have not been tested and are sold as is due to age.
Each amplifier weighs about 31lbs unpacked. I will ship worldwide!
