    Hello everybody !
    Another question...
    I need to change on my SC-35 dynaco amp, the bass potentiometer. It seems it is a 2Meg linear double. But I can't find a replacement one...
    Have you got ideas my friends ?
    Thanks for your answers !

    Not specifically mentioned but it doesn't hurt to ask- try here:

    https://www.erhard-audio.com/Accessories_Kits.html

    https://www.updatemydynaco.com/index.php

    https://dynacodesigns.wordpress.com/dynaco-design-products/

    I didn't see any at Dynakitparts.com other than bias pots.

    No affiliation or SCA-35.

    this eBay seller has a lot of dynaco parts. I don't think this will work but he may know of something:

    Thank you New2Tubez ! I look at that quickly...
    I ask myself something... What about creating ourselves our missing pots ?
    You know the "empty" pots ?

    If we mount good resistors according the VolumeControl Design soft :

    It could be possible to mount a 2Meg pot no ?

    dynaco pots were their own animal.

    Update my dynaco has some info on the PAT4 bass pot and some stepped pots in the store.
    You could shoot Dan an email and see if these would work in your SCA

    hy guys !
    I'm waiting for the empty pots to test mounting resistors on it... It seems we can solder smd resistors instead of classic resistors...
    Someone can tell me the characteristics of the different sca-35 pots ? are they linear or exponential ?
    Same question for the pas3 pots !
    Thanks !

    This Software would be nice to have, however I could not find it doing my usual search Could you point me to the web address?

    I was thinkiing using a 4 gang switch we may be able to create the PAS 3X Base /Treble pots.

    Hello !!
    Here is the link : http://www.tonnesoftware.com/
    you can find the software at the end of the page. The name is VOLUME CONTROL.
    I'm sure this program can help us to renew all pots for our dynaco's machines...
