Tube rolling my preamp with 6922EH

How much are you willing to spend?
NOS tubes are definitely the way to go but they are pricey.

Before you venture off into NOS tubes, which addmittedly can be better in many applications, try some of the alternative new production 6922/6dj8's, and see what you think of them. Try the EH, also the JJ, which sound nothing alike, and given your financial considerations and lack of real focus, may just float your boat. If you don't like either of these tubes at least you will have gained another reference when asking for advise, for example my observations of the performance of the EH. BTW the EH is not a 'bad tube' at all. Lots of folks like it!

Caveat 6922/6dj8's that are quiet and worthwhile are usually very expensive. I prefer Amperex BugleBoys, some Siemans, and Tele's. Old Yugo's (EI's) now hard to find, are probably my all around favorite. Be very careful about who you buy from, this is classic swampland territory.

I'm out of the ball park for expensive rare NOS. Would like to keep under a few hundred dollars for all (3) tubes.
Newbee, please tell me more about the Old Yugo's and why you like them so much. What time periods/years were the ones you like manufactured? How would you describe their sound qualities? What weaknesses, if any?

These sites have some good info: ( https://www.tubeworld.com/6922.htm ) (http://www.audiotubes.com/6dj8.htm) (http://home.att.net/~chimeraone/6dj8sound.html) Looks like the tubeworld URL might have to be copied and pasted for some reason.

One of the best bargains in NOS 6922s are Tungsrams from

I bought from these fellows many times back when they sold on Ebay. They were trustworthy and thir testing was reliable compared with results on my tester. If I needed more tubes from the 6922 family, I'd buy from them again.
