Hello – I have a matched pair of Red RCA 5693 6SJ7 audio pre-amp tubes.

These are sharp cutoff pentodes and the military equivalent of the 6SJ7. They are a direct replacement for the 6SJ7.

These are 10,000 hour tubes.

All tubes are tested on my calibrated TV-7/B or on my calibrated Hickok 539C. All of these tubes have been tested for transconductance, shorts, gas, leakage and life. All tubes meet or exceed manufacturer published specifications of transconductance (Gm) for the specified tube type. All tests are tested twice – prior to the listing and prior to shipping.
