From the seller: SOLID FUN MUSIC
I used same value and capacitors type as Analogman did, Panasonic for film caps and Nichicon FW for the electrolytic. Also carbon comp resistor on input and output path.
A few thing that I did differently, I used 1S2473 for clipping diodes, while Analogman used white band diode which I think it was MA150.
I also changed caps on power supply section with high grade Nichicon FG, Analogman usually did the same on most of his mods but not on his DS-1 that I currently have. And lastly, I used 1/2 watt carbon comp resistor while Analogman used 1/4 watt rating. shouldn't be any different since I use same value, and I personally handpicked the resistor to be the same value as what I found on Analogman DS-1 that I have.
I also had socket installed for the opamp. Analogman prefer stock NJM3404 (JRC) opamp, so stock opamp will be included. but just in case you want to try other opamp, I will also include opamp adapter so that you can try standard dip-8 dual opamp (last photo). personally, my favorite dual opamp for DS-1 would be old stock NE5532
The pedal currently has the chip adapter and an NE5532 installed
