Matched Pair 1950’s  NOS NIB RCA JAN-CRC-6C8G Round Black Plate Vacuum Tubes

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.
