Last week I was quite lucky because I picked a '84 Boss DD-2 and a '90 DD-3 (long chip) for about € 30 because they were sold as not working.
I took the DD2 apart, cleaned and reassembled it. Suddently it started working very well!!
When I opened I noticed it was previously "visited" by someone maybe more than once: the battery snap was changed and the tin foil was removed. Now I can heard some little noise even when the pedal is off, can that be the reason for the noise?
Now the DD3. It lights up, the clean sound is ok but when I turn it on I can listen one or two repeats at very low volume (I have to raise up the volume amp) adjusting the potentiometers (level and feedback) near to maximum. I took apart and reassembled, as DD2, but this time with no luck.
The led shine as the DD2.
I tested both pedals with a Boss 9V PSA-230 and a 9V fresh battery.
Any ideas? Maybe some bad electrolytic cap?
Thanks a lot

Have a look at this thread of comprehensive repair notes. You may find some answers there.
A great many DD-2/DD-3s of that era are failing due to components (caps being a good example to change), I should know I have two sitting on my bench that are effectively dead!
