GENUINE 1969 HEERLEN HOLLAND AMPEREX 6DJ8



ALL TUBE MUSEUM TUBES ARE TESTED IN THE "FIXED-BIAS" MODE

Most vintage tube testers test tubes by using fixed bias. So, if you are trying to compare test results between the AT1000 and other testers, this is the best way. The Tube Museum ALWAYS choose the "fixed bias mode"  while testing our tubes.  We only test in the "fixed-bias" circuit, this way drift or aging of the tube will not be compensated for, and your tube’s TRUE performance will be displayed on the LCD display, so you KNOW what you are REALLY buying!



Here is the "6DJ8" Amplitrex Set-Up Data Screen.  The heater is a TRUE 6.3 volts, testing at the correct 90 eP with a mA Specification of the true factory data of 15.0mA and a GM or mutual-conductance (also known as mA/V) of 12.5mA/V or 12,500 Gm.


SEE THE AMPLITREX AT1000 DIGITAL TEST-RESULT PROOF!


You will never find such a TIGHTLY Balanced & Matched Pair anywhere again! 



BALANCED & MATCHED TUBES! 


There's no fooling around at the Tube Museum with meaningless claims like "tests strong!", or some arbitrary number like "the tube test 82 with a minimum of 75" and no maximum stated! We always give you the test results FACTORY-DATA so you can compare with the real factory data sheets in mA and mA/V, just like the original factory data sheet! (specifications).


* Tested in the fixed-bias mode like Hickok testers!

You will never find such a TIGHTLY Balanced & Matched Pair anywhere again!

PASSED THE AMPLITREX DIGITAL TESTS = NO GAS and NO HEATER-TO-CATHODE LEAKS!
