no idea who is selling them, but in general, e-bay is a crap shoot for tubes.
Which tubes to roll
I just picked up a Cary CAD 120S. I wasn't planning on rolling tubes so soon but one output tube was missing so I've started looking into it.
Right now it has KT88EHs as the power output tubes. I was thinking about trying some different ones, say, the SEDs but I was wondering - which tube have more of an effect on the output: the the input 6NS7s or the KT88s?
I noticed on Ebay they have a matched octet of winged-c SEDs for $400 that are supposed to be the original Svetlanas.
