  • Twin Tube Classic pot problem

    My beloved Twin Tube Classic started to do tricks. Both vol pots on the Rhythm channel and on the Lead Channel stopped working. They let the sound through, foggy, even when rolled to zero.

    Here is a video I made about this: http://www.youtube.com/watch?v=RxhUY1owO_E

    When I tweak the Rhythm vol pot to zero with a bit force, it lets all the noice thru. And when I knock the Lead vol pot's knob, it lets all the noice thru, too.

    Obviously I have to change the pots (?). I opened the box and checked them and I surprised: they are not standard looking pots with three connectors but six!

    I have read the schematics but did not figure out, what is the model and type of the mystery pots. Does anyone know it?

    I had that issue at one time. I ended up sending it in for repair.

        Hi! I am sorry but I can't help. Believe or not the pots of my TTC did not snap, crackle or pop anymore soon after that message! Not any disturbing sounds at all. Weird. Mystic. Supernatural.
        So I sold it! And went back to Old Faithful H&K Tube Factor. (Which started it's own show because of its broken transformer, but it is another story. Oh my.)
        I hope You find a solution.

          Are ALL the pots noisy.?
          Did you try cleaning them.?
          Kind of hard to believe that they all need replacing. If so, you should be able to purchase new pots from any of the usual suspects.

            No, not all potentiometers, only for The volume one.
            i tried to find new pots, but this one is not usual, it has not 3 contacts but 4 and 2 for Grounding.
            here's how it looks:

                Try ALPHA Potentiometers @ www.alphapotentiometers.net/html/11mm_pot_4.html
                You'll possibly find the style you need listed as Model #3RP/1112N. The pots in question may have four through-hole terminals as well as two case grounds, but according to the ALPHA website the #4 terminal is a dummy and NC. And, additionally you will need to know the impedance specs, shaft style, and Taper for each of the pots you need to replace. This information is readily available @ the website quoted above.
                Hope this helps!
