Tubes for CJ EV-1 phono pre


My second set of tubes from CJ has finally expired, so I'm looking for suggestions and opinions on replacing the tubes for my CJ EV-1 phono pre. Tubes from CJ's stock sound just fine, but I'm not experienced at tube rolling, so should I order from CJ again as they recommend, or take a chance and seek else where? If you have tried tubes other then from CJ's stock on your CJ gear then please fill me in on your experience... I'd love to hear about it.

What tubes are in it?
If you are going to try Old Stock tubes you will pay a premium for gauranteed quiet performers. Otherwise finding "phono grade" tubes is a crapshoot.
Thanks Mechans. The tubes that are in it are:

two 12AX7's
one 5751
one 12AU7

Paying a premium is fine. Where are some good places to buy Old Stock tubes? ..Any recommendations?
I used to own the EV-1 and I used NOS Mullards (12AX7s and 12AU7) which sounded really nice. I think I used a NOS GE 5751. I bought all of these tubes from Upscale Audio. Get the platinum grade tubes and noise will not be a problem.
