Boss DD-3 Help

[96ecss]

Hi,

I have a Boss DD-3 that doesn't work. Here is the problem; when turned on, there is no Delay signal. You can still hear the dry signal. There is alot of white noise or static coming out. It increases when you turn up the Level pot and the Delay Time pot. I did a search but didn't find any info on it.

Any help would be greatly appreciated.

I fixed one that had faulty Fet for the bypass switching, take this schematic of the DD-2 http://www.freeinfosociety.com/electronics/schematics/audio/pictures/bossdd2.png
I changed the Q8 fet.
