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.

You should consider the new Tung Sol KT120 tubes.

The Genalex are great sounding tubes and reliable.

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...

If you are on a budget and can't go to the Tung Sol KT-120 tubes I would say go for JJ KT88 Blue Glass tubes. In my experience with these tubes the sound and tone is clean but bass could be a bit thick. I've read that the JJ 6550 type tubes are just as clean sounding but the bass isn't as thick as the JJ KT88s.

One thing I find with the JJ KT88 tubes is that in my Jolida JD-502P it gets biased quickly upon turn on.
