    Pas 3x volume fluctuations.

    Post by markc2 on Mon Sep 03, 2012 12:40 am

    I have a PAS 3x and it's been a ball so far. Just recently it started to fluctuate like the volume was being turned from regular to almost off at a very quick pace.

    Was wondering if this has happened to anyone else.

    Does the 12x4 affect the sound of the Pas3.

    Really love this pre-amp.

    After hearing a Shindo Preamp sunny in my system was amazed how quiet the Dynaco was.

    Try unplugging and plugging the 12X4 tube a few times to see if the problem goes away.

    if it's an original 50 year old volume control, it's probably going bad

    I just ordered a NOS 12x4 tube, and I am trying to pick a cool person to fix it.

    Thanks for the help thus far :-)

    where are you located? Lots of qualified people on this forum that could fix it for you!
    I'm in WA, Troy in SD, Sal in NJ, maybe some others.

    re-plugged the 12x4 and presto, instant music again. Still being careful with the volume.

    Thanks for the help

    Are you sure that is the pas the problem?
    Some time ago i think the same think but the problem was the source.
    Try with another source.

    All the best

    Hi Tiziano73,

    I just came from an other pre-amp to this one, unfortunetly its the pas 3. I found a person who's been working on Dynaco stuff for a long while and I just shipped it off for its "restoration".

    No tunes for now :-(

    The fix did work, but I thought just to make sure all is happy in Pas 3x land I would send it off for it's 40 year checkup.
