Re-biasing a CJ Premier 8

I guess the retube price includes the 12 driver tubes 6fq7 (8)and 5751's(4)----These make a big difference to be sure.

CJ quote came from the company itself (they have been very supportive, kind and informative), again - it would be around 600 US per amp.

The Svet 6550c quote comes from www.sovetk.com, under Svetlana section, my friend has dealer pricing and kindly passing thru.

I am NOT including the driver set, which look OK.

I need to take a decision in the next 48 hours or so (flying to Detroit on Sunday from Mexico) - I have the feeling that I will run the "risk" of re-tubing and keep the Premiers 8 for me.

Believe me the drive tubes matter, more than you think.When you finally get around to getting some cryoed ones;you'll understand.

I would concurr with avguygeorge on the influence of the input and driver tubes. That said: Both the 6fq7's and the 5751's in the amplifiers should give you at least 3000 hours of life before replacement [unless they go noisey or microphonic]. The nos triple mica sylvania 5751's as well as the rca triple mica black plates can have a profound impact on the resolution and bass drive in the CJ amplifiers.

I was placing more focus to the output tubes, thanks for the info.
