i have tried the EY500A from Telefunken in my ZDSE and it changes the sound. A decent amount more body. I didn't have luck matching them though. Not sure if the mismatch is what changes the sound. It should just add some 60 hz distortion. I assume they have to be matched in the 2A3 as well. i also tried some Valvo's and they sound exactly like the stock ones. Hard to find I thought. Didn't know that the 6EC4 would work as well.

Yeah 6ec4 and ey500 are the same. Anyone know what the difference the A version of these tubes make.
