    It could be a coincidental modification but here is a 2500 with the same potentiometer.

    On some JCM900 amps, it is R5.
    But on other JCM900 amps the resistor has a different number.
    Plus, there is an R5 in the preamp and another R5 in the power amp.

    And so viewers, be careful which resistor that you bypass and make sure it's the correct resistor.
    (should be a bypass for a cathode resistor in the preamp)
    This mod has 3 wires to the pot,
    the other amp has 2 wires.
    It's a different board from the other amp.

    ive zoomed that image up, the mod doesn't look dodgy at all.
    I've got porn eyes from putting my eyes way close to the screen, permanently damaged.
    it does appear as if r8 has a mod too.

    dude, 9 holes?

    two armpits = 2
    the uh, front mid ( normal channel) =1
    the uh, rear mid (brown sound channel) =1
    the mouth = 1
    are you telling me the knee armpits are a thing?
    And the ears? are you telling me to shove it in their ears too?

    ampmadscientist, I'm surprised by posts 23 and 26.

    did you not recognize your own creation?

    So you didn't recognize the mod, and now someone else says they created it?
    I hate this stuff, it's wrong.

    What do you mean by “it’s wrong”?

    It means that someone spent hours, maybe days figuring this stuff out, it's not easy, it's hard and time consuming, and then someone else takes the credit.
    I believe it's happened before.

    When you work out a mod, it's burned in your brain, you see it in your sleep, as if you don't recognize it once you see it.
    I know my work the second I see it, that very second.
