Hello – I have a closely matched pair of Tung-Sol 6SU7WGT 6SU7GT 6188 Mil-Spec tubes for sale.

The 6SU7 6188 is a direct replacement for the 6SL7GT

These tubes have black plates and "D" getters. They have matching 1960 date codes. One tube has a chip on the lip which can be seen in the pictures.
This has no effect on the tube.

TV-7/B test results: 50/52 and 50/50. Minimum is 32.

They have also been checked for noise and microphonics in the phono stage 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.

Please check out my other ad’s on Audiogon.
