Hello – I have a matched quad of RCA Clear Top 6CG7 6FQ7 tubes for sale.
These tubes have gray ladder plates, “D” side getters and the shield between the two plates. These tubes were manufactured in the early 1960’s.
These are NOS testing tubes.
TV-7/B test results: 105/105, 105/105, 100/100 and 105/105. Minimum is 50.
All tubes are tested on my Dan Nelson 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.
