Hello – I have a matched pair of RCA 12BH7A tubes for sale.
These tubes are NOS and new in the box.
These tubes have gray ladder plates and halo getters. They were made in the early 1960's.
TV-7/B test results: 85/85 and 90/90. Minimum is 30.
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.
