[COLOR=000000]Are PCC88 / 7DJ8 tube compatible with Schiit amps? I have the Valhalla 2 amp, if I roll the 6N1P dual triode input tube with (6922 / 6DJ8 / 7308 / PCC88) is the difference appreciable? I don't want to spend my hard earned cashed on an unnecessary and incompatible upgrade, the stock 6N1P tubes under my magnifier appear to have gold grids.[/COLOR]
[COLOR=000000]It would be nice if team Schiit would shed some light on tube swapping, like a tube rolling chart something. I'm sure that everybody has noticed by now that vintage tubes are not cheap, it would be nice if Schiit would chime in on this because the cost of better tubes is eating into my buy more Schiit budget.[/COLOR]
I'm sorry I got lost in the mix, the tube info is here, maybe its the format or something, when things get wordy my mind wanders, I'm looking for something dumbed down like this link

http://www.audiotubes.com/6dj8.htm 6922 JJ Gold Pin, "New Stock original box. A very decent current production 6922 from the Slovak Republic, carefully tested and matched by us. These have gold pins and are among the best of the current production 6922 tubes.
TOP SECRET: These are made in the same factory that makes the tubes for EAT, which are much more costly! Singles are $40 each, MATCHED PAIRS JUST $80.00 PER PAIR! These come the closest to the NOS European sound, and at a great price!"
Furthermore, 6DJ8 Matsu****a Japan (Mullard) factory made, "1970s vintage New Old Stock white box. Nice Japan made 6DJ8 tubes from a factory that was set up by Mullard, and these tubes have similar sonics to Mullard. Most are made for Amperex, some for RCA or National. MATCHED PAIRS JUST $50.00 PER PAIR!
Better than any Russian or Chinese junk, and at a great price!"
"When it comes to warmth, no other tube can top this jewel from the British crown. Silky highs, a liquid midrange, and awesome deep bass give this tube its deserved reputation for warmth and full sonics." Mullard
Cca Philips Holland made for Valvo (ultra premium 6DJ8/6922) "The Cca is one of the "Holy Grail" tubes in the 6922/7308 family, and
probably the best audiophile 6DJ8 type ever made, at any time. They were originally made for the German Government for use in telecommunications where low noise and long life were critical."
