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

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.

my room is damped and therefore nit ispossible that changes in high frequencies brought about by chaningibg the tubes in my various cj amps were not as noticeable as in a very live room.

i have noticed the damping to affect the sound of other tweaks and even reduce differences between the sound of preamps anad amps, but not eliminate them. i can still hear differences in texture of hifg frequencies betweeen ss amps and tube amps, its just that some of the resolution in the treble may be attenuated as a result of the room treatment i use,

i think it is only fair to reveal this relevant material.

by all means try different tubes and see what you hear.

i hope this helps.
