Pair RCA 6LQ6 6JE6C Tubes NOS Ham Radio Transmitter Amplifier Final Matched 1969
RCA 6LQ6 6JE6C NOS Ham Radio Transmitter Amplifier Tube Finals. Matched Date code of CH on each = January 1969. Tubes show no signs of internal discoloration on the silver flashing, one has a little discoloration on the anode cap, but these have had no or miniscule use. Tested on a Hickok 539B tube tester for mutual conductance. Test at 7000 & 6700 uM micromohos mutual conductance.
Is the minimum acceptable Gm value. Please note the 539B tube tester is analog, so the test values may differ slightly from tester to tester.
Values are added as a means to show the tubes indeed test excellent, not an exact science. Your results can/may vary, but tubes are indeed good and strong.
