I had a pair of V4s and usd them on the MR/tweeter panels of Eminent Tech. 8s. I used both the original Chinese '88s and a set of Ei KT90s I already had. Frankly, not being a GEA and being more of a tin-eared audiofool, I couldn't distinguish differences in their sounds, altho I'm sure some existed. If I were to buy new OP tubes for it, they'd be the solid-plate Penta KT88SCs that are getting raves on the Tube Asylum. On frontend tubes, I bought and tried MANY-different ones, but, again, couldn't distinguish between their sounds. I still have LOTS of 12FQ' and 'BH7s; e-mail me at jeffreybehr(at)cox(dot)net if you'd like more info; I'd love to be rid of them.
BTW I improved lots of parts in the V4s and improved its sound quality, mostly in clarity, cleanliness. Let me know if you'd like that info.
