Vintage 1950's NOS NIB RCA JAN-CRC-6C8G Round Black Plate Vacuum Tube
An absolutely stunning tube. The 6C8G is electrically equivalent to the 6SL7 and actually predates the tube. It has a different pinout with a plate cap on top and will require an adapter to work as a 6SL7 which is not included. These are military issue, have black round plates and were made in 1950.
Tested at NOS levels or above for Gm on a calibrated Hickok TV-7. Tested for shorts, leaks gas. Fully guaranteed.
