JJ E88CC Exact Replacement (also known as the 6922, 6DJ8 and ECC88) is a high-quality double-triode valve originally introduced by Mullard in the 1950s. They rearranged the part number from the expected ECC88 to E88CC to highlight that it’s designed as a long service valve. This differs from ruggedised valves made to withstand excessive vibration. The E88CC provides smooth mids and highs with a lot of detail.
PLEASE NOTE: the E88CC is NOT pin compatible with ECC83/12AX7 valves, and not designed to replace them.
We test each valve in-house in addition to full factory testing by JJ Electronic to assure you of getting a quality product.
Includes our class leading 180 day warranty.
The alternative part numbers for this valve are ECC88, 6922, 6DJ8 and the Chinese 6N11.
