Tung-Sol 5U4GB Rectifier Tubes - Matched Pair

Hello – I have a matched pair of Tung-Sol 5U4GB Rectifier tubes for sale.

These tubes have ribbed black plates and dual halo side getters near the tops of the tubes. They were made in the early 1960's.

TV-7/B test results: 62/62 and 62/65. Minimum is 40.

They also have been checked in the power supply of my DIY pre-amp and are dead quiet.

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.
