Ref Failed capacitors thank you for the info,Just checking the value of these capacitors C30 =47uF 63volt C31 + 10uF 16volt C34 10uF 16volt.this is what I see is the circuit diagram is this right?

Thank you again

Values are correct. Don't worry about the voltage - as long as they are 16V or higher and physically fit (space is tight).

Hi all, hoping someone can help me with my DD-2 D6 diode. The diode I removed from the pedal either had no line indicating polarity or it burnt off when the diode failed. Can anyone help me out in terms of its orientation? I'm a novice at all this stuff, but in the schematic, it looks like it's orientation is the opposite of all the other diodes. The other diodes have their cathodes (+ end) facing toward the top of the pedal. Should the cathode for D6 be facing the board?

I can't recall off-hand, but will be able to answer definitively tonight after I finish work.

Oh thank you - that would be amazing. I realized I didn't ask the question very well but I think you know what I'm trying to ask. Maybe a better way of asking is whether the side with the shortest leg on the original diode the anode or the cathode? I appreciate your help!

Stripe goes in the hole closest to the 4164 memory chips.
