The E88CC also known as the 6922 is a high quality double triode originally introduced by Mullard in the 1950’s. They re-arranged the part number from the expected ECC88 to E88CC to highlight that it is designed as a long service valve. This is different from a ruggedised valve .It provides very smooth mids and high end with a lot of detail.
Note that while this valve can be classed like an ECC83 /12AX7 :
The E88CC is NOT pin compatible and not designed to replace an ECC83/12AX7
We test each valve ourselves in addition to full factory testing by JJ Electronic to assure you of getting a quality product
Long service means lasting a long time. Ruggedised is designed to withstand a lot of vibration. The alternative part numbers are ECC88, 6922,6DJ8 and the Chinese 6N11
