ARC LS22 and pre tubes

Are you sure all 8 are bad? Usually you only use 1 main pair and 1 or 2 inputs? Save you a few tubes that way.

There is a recent ad here on Audiogon for some Philips JAN 6922 for $7 bucks each. These are pretty decent tubes, especially for that kind of money.

These are NOT my tubes and I have no affiliation with the seller, just passing on a good deal.

I assume you are looking for new production tubes, and something rugged and quiet (ARC's seem to like them best), and want something with a bit more warmth than Sovteks. My first choice would be EH6922's and, if you want a bit more color but not as balanced, the JJ's are OK too. I use them both, but neither in my ARC SP10 where I use NOS 6h23's.

FWIW
