  • Vintage fender sidekick tube 20r 1986 model burnt resistors!

    Good day!

    So I accidentally plugged my amp to a 110V power outlet.

    The amp required 100V ONLY!

    It worked (for a while) then smoke came out from the back and the volume dropped down to barely audible.

    I opened the amp. Checked the fuse, tubes, caps, etc.

    I found out that the resistors R57 and R58 were burnt.


    Problem is, I don't know the values of these two Resistors. Can't rely on the color coding either because they turned black. I can't replace them without their values.

    I searched the internet for Schematics but found nothing.
    I emailed fender but still they have nothing.

    It's for us to say what the values would be since we lack the proper documentation. Unfortunately, since this amp was produced around a transitional period when CBS sold Fender in the Mid 1980s none of that information was transferred and we were not able to reacquire it while we rebuilt the company. I apologize we could not be of more assistance

    I'm not an amp expert and I badly need help. Thank you!
