Re-biasing a CJ Premier 8

I am considering to get a used CJ Premier 8 amp, current tubes are 75%-50% of their life (12 6550 per side) and dealer recommends me to re-tube both units.

1.- Which are the best options considering a high price/performance ratio?

2.- Any word on domestic Svetlanas vs fying "c" options?

3.- What about trying KT90´s?

Thanks for your feedback.

Since you are just starting out with these amps, I would suggest the Svetlana (SED) flying C. They are very reliable and produce a fairly balanced tone. The KT90's may have tighter bass and maybe a bit brighter tone - my biggest reservation is about the reliability of current production KT90's. Sonically, its your choice.

Fernando, I don't know where you are getting your price quotes, but I just check the web site of Triode Electronic's. He is selling matched quads of SED (the old Svetlana brand) for 95.90. According to my calculations that would bring the cost of retubing your amps to less than $400. I've used him many times. Very reliable and the product is guaranteed. I'm using these tubes in my amps at this time - I've yet to have a premature failure.
