ARC LS22 and pre tubes


I am looking for 8 "good tubes" to replace the eight Sovtek 6922 with a low budget. Please give me an advice.

Thanks

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
Thank you to all. Actually, comparing to McIntosh C20 preamp, ARC LS22 ( I just bought) is lacking of high and low frequency. It is OK in term of noise ( I think it is better than Mc Intosh C20). So, I am not sure what causes the problems I hope replacing tubes will fix the problem! I am going to try some tubes and let you guys know the results. Feel free to recommend.

Thanks
Hi Elevick,

Thanks for your tip. Do you know exactly how many tube (and which ones) used in LS22 for unbalance? I don't use balance cables so i can forget it and just replace tubes that i need. In the other words, which tubes are for balance purposes?
Thanks for your help.
You need the manual or schematics usually. AR will help if you call them. You need a pair of tubes for the gain stage (Most likely the pair closest to the outputs) and a pair for each input. The sockets should be labeled in some way such as v1, v2, v3 and so on.
If you only use cd, you only need 4 tubes.
