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

I long ago gave up trying to get tone from the critical positions. The cathode follower tube/circuit provides no gain but affects the output so that you can drive long runs of IC's. Google it - I'm sure there are many thorough explanations there.

I have 2 ls22 and love them, they're essentially a ref2 without a tube regulated power supply. Transformer is massive, sound is great, and the 6922 is a special tube with excellent sonics!
