Hello – I have a matched pair of Red RCA 5693 6SJ7 Tubes for sale.
One tube is NOS and new in the box. The other is not but they test very closely and date codes are a few weeks apart. The RCA "Special Red" tubes (5690, 5691, 5692, 5693) were designed for 10,000 hours of use. RCA claimed the 5693 tube could withstand shocks of 100 G's for extended periods of time!
The 5693 is a direct replacement for the 6SJ7. They have 1958 date codes.
TV-7/B test results: 82 and 80. Minimum is 40.
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.
