Re-biasing a CJ Premier 8

I used Ei KT90s in my Elevens very succesfully. They seem to be loved by many.

Enjoy your Eights; they're fabulous amps

BTW, I think you meant 'retubing'.
.

I'm sure you meant 8 per side. I also say, use the old tubes to get a fix on what they sound like---then you will notice the dif. when you do retube.

Fernando,the friend of mine using the Premier 8 is a former reviewer for TAS.I had the retubing discussion with him,and,he continues to use the tubes supplied by CJ themselves.He had spoken with Lew Johnson who feels the stock tubes are fine.This is not to say that tube rolling won't be better,but it could save you some money,as well as the possibility that you may actually get best performance from CJ's own stock.

I'd be surprised if c-j is selling their presumed-selected-and-burned-in 6550s for less than the $70 per pair you can buy Ei KT90s for.

Thanks to all for your feedback.

I have a quotation from CJ at about $650 per amp for a full retube set, those are GE if I am correct.

I also have a friend who can get Svets 6550c, which some say have the best sonic behaviour in terms of tonality and dynamics, this route will cost mearound $500 for both amps.

I currently have Sovteks 6550, sounding great to my ears but at the end of their operational life.
