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.

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.
