RCA JAN JRC 12AT7WA Black Plates
Military spec. tubes from 1960's with "12AX7/12AU7" type small black ribbed plates and o-getter. These have extra support posts on sides.
This tube is very low in microphonics and noise due to its rugged construction. A guitar player favorite! Matched pairs and quartets available.

The best in the stock. Lowest noise and microphony with the tightest balanced

large volumes of our stock.

Low noise and microphonics with a section balance typically between 15% and 20%,
but may be higher depending on available stock.
Grade C -
Lowest noise but slightly microphonic. Section balance will be similar to Grade
A or B. This grade is only suitable for use in the driver stage of an

Absolutely perfect choice!I bought a pair of them.
