I don't think the 6A still uses the 22DE4. I seem to remember Cayin changed it to 25AX4 at some point. Cayin's website still says 22DE4, but Moon Audio says their 6A has 17AX4 rectifiers. And I believe the 3A and 2A also use the 17AX4. The 300 is the only amp that still uses the 22DE4. So if you are shopping for a 3A or 6A, I would confirm with the seller which rectifiers it has to be sure you get what you want. It's a little confusing since I think at one point the 300, 6A, and 3A all came with 22DE4. Maybe Andy Kong can clear this up.
