What tubes should I buy?

Im running a tungsol in v1 jj in 2,3,4 and sovtek lps in loop and PI. Loop is now dead silent for me... Tried a mullard cr4004 in v2,3,4 and didnt didnt like it, made the amp very boomy. Id like to try all tungsol in v1-v4 but im pretty happy with what i i have right now

I have a few Sovtek LPS, might try those in PI for giggles. Forgot to mention in previous post that I got my Archon 50 used & it had a Fender-branded 12AX7 in the V5 PI slot- everything else were the stock JJs, not sure if previous owner swapped it or if that was from the factory.
