JAN 6V6 Y RCA Metal Amp Tubes NOS ~ Tested Strong! These new old stock 6V6Y metal octal beam power tubes have never been used, stored away for years. Made by RCA for the U.S. Joint Army/Navy. Unusual version of the popular amplifier tube with brown Micanol base. Tubes are date coded 68-43. Vintage military type boxes dated 9/68 in good condition. Tubes tested as strong on my Hickok tester: matched at 4300 each in mutual conductance, with 4100 as average new, gas and shorts tests good. |
