Power tubes are electrically matched so each tube will have the similar amount of “idle” plate current and amplification characteristics when used in an amplifier. This is done so the tubes can work together in your amp giving you optimal sound quality and tube longevity. Matched tubes also receive extra quality checks to reduce the possibility of getting a faulty power tube that may have slipped by!
The
Sencore TC28
has the
Most Sensitive Leakage Detection System
than any Tester in it's class, and a
Very Accurate
method for testing
Tube Life...
The
Jackson Dynamic 648R
rivals the
Hickok Dynamic Mutual Conductance Tester
, and is the preferred choice of many world-class technicians and engineers!
Many hours are invested in proper testing in order to guarantee the best in
Quality
and
Performance!

I place every 6SN7 Quad, Set or Single into my
YaQin MC-100B
Push-Pull Tube Amp...
Then I listen!
I use a
Sencore TC28
, a fully calibrated
Jackson Dynamic 648R
and my ears!
The tubes are put through a
Life Test
and each plate is
warmed
and
measured for emission, leaks and shorts...  Each tube is thoroughly inspected, they are described accurately and listed based on fair value...  I am priced well under most sources and have a better quality selection!

I mark every tube in order to avoid tube rolling...
