Russian Tubes or Old "American" Tubes (built where ever)?


Currently I have Aperex ECC88 tubes in a CJ 17 LS pre-amp and a backup set of Russian electro-harmonix 6922EH tubes for the pre-amp. The Aperex tubes are failing. The amps are solid state Mac 601's

What type of tubes (manufacturers/time period) would you guys recommend? Are the Russian tubes any good? Buying legacy tubes from 50 years ago gets expensive. I'm looking for a great price/performance ratio, but I lean toward performance. Do the Russian Tubes compete with the old tubes or should I "bite the bullet"?

I know folks can get passionate about this - I'm not an idiot; I would like to hear some experienced opinions about the relative merit of various tubes for this particular pre-amp. I'll then go check my budget (in secret - I'm married).

Thanks.

After rolling in tubes for years (painful): I currently love (and yes, it is actual love) the new Gold Lion 12AX7s, the Tung Sol (Russian) KT150s, and NOS Mullard 12AT7s, and am also an idiot. Wait…I mean I'm also NOT an idiot…and all of the above mentioned tubes are not idiotically expensive as far as these things go.
Bought my Mullard NOS 4024s (12AT7s) from thetubestore.com, and the gold pin 6201 version (also Mullard NOS) from Upscale Audio, as that's the  only place that had these (that I found anyway). I can recommend both of these vendors as easy to deal with and knowledgeable with well designed websites (unlike the confusing sites of some other tube vendors).
I buy small preamp type tubes, matched and balanced, 12AX7s and 12At7s generally, from familiar dealers (thetubestore, Upscale), but the KT120s and KT150s as "factory" matched quads have served me well from Ebay sellers. If they tested poorly or had to be returned to those sellers, it would result in poor ratings unlike the 100% positive ratings of the dealers I use.
