    NEO-MVH 4 Slot, Crackling sound

    Did the usual and replaced all the caps in the sound section. Went as far as replacing and socketing a few of the amps, dac, and ha13001. Still getting the same results. Anyone have any ideas what this might be caused by? It seems to be a thermal issue, because if I let it sit for a bit, it'll start up fine, but within 10-15 seconds it'll start crackling again.

    Playing it on a mono cab, so it does sound already a little strange, but you can hear what I'm talking about in this video.

    Here's the board

    Had the same problem on a 6slot I recently got
    Did a cap kit on sound section and problem didn't go away;(
    Turns out it was the actual volume slider pot.replace it with one from a parts board and it's working like new again
    i hope that helps

    Huh, I cleaned it fairly well, but I'll try swapping it out.

    Swapped out the volume slider. Still no go, thinking about tackling the ym2610.

    I have the same problem with one of my 4-slot boards. I'll be interested what you find out.

    Put a new 64 pin socket in and a YM2610. Fixed my issue.
