Fried my Boss ds-2 with wrong polarity adaptor.

Topic explains the problem, however the pedal works with battery, but makes way too dirty and unstable sound. The one thing i know is that my protection diode is dead, however there may be some other damaged parts, or maybe dead protection diode should make the sound worse?? If not, i don't know how to find other damaged parts :S. Here's the original scheme:


Where can i find the specifications of that protection diode (D2) to replace it?
Any suggestions about other parts, damage and fixing?

That diode can be replaced with a 1A diode. Your easiest candidate would be a 1N4001. Definitely a good place to start to troubleshoot your problems.

Once you have replaced that, check your voltages coming out of Q7. If those are good, you need to check voltages on all of the ICs, transistors, etc.

Take a look at the debugging thread that is at the top of the building your own stomp boxes sub. It gives invaluable info on how to fix problems like these.

Good Luck
