The ECC88 tube type is equivalent to the North American 6922 / 6DJ8 tube and can be used in any 6922, 6DJ8 or E88CC/ECC88 circuit.

Bass for open headphones
Recieved a pair of these as a gift for my headphone amp.
If you find the bottom end of your open cans lacking, these are a fine solution, although it comes at the expense of the high end--still crisp, but not pronounced and partially buried by the low boost (especially in bass-heavy music...)

Is NOS still worth the price?
This are long lasting tubes with good sound and tight tolerances. I find them expensive, considering some new production E88CCs became comparable in sound quality, although not lasting as long.
