anyone know the best tubes for pv10al.......

i currently have RCA's and the sound is bigger,more detail and dynamic, but ive lost the focus and soundstage that i love with the original tubes. which were some unknow german brand. i quess this is tube rolling time for me. any experiences with the mullards, tungsol, telefunkens, amperex or any other tube youve had succuss with would be greatly appreciated. im looking for image, soundstage, focus, long life, gain, detail, and headroom extension. i dont want a rolled off sounding dark tube. please let know, thank you for your help in advance.

I like Siemans the best, the Mullards are my second favorite. CJ told me the E. German tubes are subject to arcing which happened to me and blew out my volume pot.

i have owned the following tube preamps:

cj pv 5, pv8, premier 2 and premier 3.

i have found that the circuit design of these preamps is not very tube sensitive.

if you contact customer service, he will probably suggest that while tube rolling may alter the sound, its affect is small.

if you are already experiencing detail, how are you lacking focus. both detial and focus are highly correlated with each other.

thanks mrtennis for those tidbits. i currently have amperex, rca, tungsol, phillips mini watts that i just got. and will be trying the mullards and siemens next. i feel the tungsol have the best sound so far.... but all have their strengths and weakness.

Hi Mrtennis, your experience with rolling tubes in cj amps is a little surprising to me. I've rolled tubes in all my cjs: Premiers 5, 11a & 17LS. I have been gratified in each instance but in particular, with the 17LS. Installing NOS Amperex 6922s was a revelation.
