The Tesla factory was known for making some outstanding valves. The Original EL34 better in terms of microphonics and reliability than the famous Mullard EL34, hence Marshall used the Tesla EL34 from the mid 1970ís onwards. The frame grid E83CC was due to its construction the most expensive of it type to produce. Still to this day it is one of the best sounding ECC83/12AX7 types ever made. These are just a few of an endless list of pioneering valves produced by this great Czechoslovakian factory that sadly is no longer with us.
