The new JJ EL34 II is a great addition to JJ EL34 family of valves. It crunches up really well without losing definition. It is not as aggressive as the E34L.Platinum Matched & TestedWe burn-in these valves for a minimum of 30-40 hours before matching. The reason we do this is to 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 tube 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.These are Platinum Matched & Tested with state of the art digital & analogue measuring equipment for
