Svetlana v. Genalex KT88 Tubes?

I have a pair of conrad-johnson Premier 8A monoblocks, each with 8 6550 tubes (plus six more small tubes). I have had two blow in the last week, and most are glowing very purple. They are currently Svetlana Winged C tubes. Someone has recommended Genalex KT88 tubes instead. Any opinions?

Thanks,

B.

I should probably mention they are new, Russian-made Genalex tubes, not originals.

You should consider the new Tung Sol KT120 tubes.

I never have power tubes "blow" unless something else is wrong. You should get this check out before any new tubes are added. It might just be your bias but who knows...
