JJ 6L6 GC

The JJ 6L6GC is a high quality 6L6 valve for both guitar and hi-fi amplifiers. It is open and articulate and has a great tone with sparkling highs, warm mids, and controlled bass response.

Platinum Matched & Tested

All our power-amp valves are burned in under load on our burn-in racks for at least 24 hours. The filaments are powered and voltage is also applied to the plate to simulate real use. The reason we do this is get rid of any faulty or weak valves and as a pre-grading process to allow the plate/grid mechanism to relax into it's rest position. Tiny differences in construction make for enormous differences in electrical characteristics, and thus if a valve is graded after it's been burned in then the measured characteristics hold true over its lifespan to a greater extent.

This seems simple but it's amazing how many vendors ignore it. It's the reason so many people complain about poorly graded valves.
