DM3 restoration, noise and static

[sgmezei]

Hey folks!

A buddy gave me his boss DM3 to fix. It has a static noise buildup that goes away if you shake it or lift it it up and put it down. The delay sounds great and works well. The noise does not cut out the output. I checked the solder joints, jacks, and pots and do not see anything wrong yet. Everything is tight and not shorting out that I can see.

Is this common? I have an old DM2 and have not ha this issue.

Could it be that the electrolytic caps are worn out?

Thanks team!

Bump!

I just wanted to get another opinion before I start replacing the electrolytics. There is like 25 of them......

Also, if I do do that, there are some super low polarized values I havent seen before. Like 0.1 uf electrolytic. Is it alright to use a "normal" film cap here?
