RCA 6LQ6 6JE6C Ham Radio Transmitter Amplifier Tube Finals
Date code of CH = January 1969
Beautiful tube inside and out an a new old stock tube should be with the silver getter flashing inside the glass is intact and no signs is usage. with the tube being 50+ years ago, there's always a possibility it had minir use. however the test results and physical condition indicate new.
Tested on a Hickok 539B tube tester for mutual conductance
Tested at 6250 uM micromohos mutual conductance.
5800 uM micromhos 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.
