Ok. I tested for continuity. I got continuity from the right side pad only of R40(470k), to the right hand pad of C20. Continuity from the left pad only of R41(100k), to the left pad of C20. You can also see the traces from these points on the back and front of the board. Just to clarify I...

I’m preparing to build the Cepheid Chorus attempting to use parts as close to the original as possible. I’m mainly using the article on electrosmash.com as reference. One part has me stumped. What I’m finding in examining old pedals is there absence of box caps. The Cepheid calls for a 1uf box...

Took some time to just turn up and jam out on my Distortion 250 and Muroidea builds. I could not be happier with the tones I’m getting from both. The Muroidea holds up against my vintage RAT. While I don’t have an original D+, the tones I’m getting from the D. 250 are amazing and inspiring. It’s...

I think I I understand. A couple questions; Everything still works leaving the second diode space empty? How are the diodes actually attached to the switch? Apologies if these questions are elementary. I’m only a few months into all this.

Figuring out how to integrate switches is definitely high on my list of things to learn.

Right on! Thanks for sharing. It’s been really encouraging and validating seeing others who’ve tracked along my same line of thinking. I’m familiar with a few on that list. I’ll have to look into the others. I could pin down most of the major difference I was interested in between the D+ and...

Awesome! You took the same approach I did with Distortion 250 pcb. Great looking pedal. Rad you’re utilizing some Drunk Beaver design as well. The Drunk Beaver BAT is what ultimately inspired me to start building. Vitalii helped me through my first pedal mod endeavors. I’d actually given up...

Nice! All the parts I used were new besides the NOS Op Amp and the diodes. I’ve just been trying to see if using parts like the old pedals would yield any particularly desirable results.

I’m partial to the minimalist aesthetic. I like subtle nods to the original design. Like the knobs. And of course the yellow LED being a nod to the original D+ enclosure.

I thought I’d get flak for having so many sockets, as I often see them advised against. Also chasing mojo with with less recommended part choices.

Before you roast my build let me explain. The purpose of this build was to refine my building skills, experiment with vintage style components, and be able to try mods and variations without soldering(I don’t have a breadboard). This is my fourth build and I feel pretty good about it. Some...

@manfesto thank you. I’m very new to all this. You and the help of others on this forum have been invaluable. I sincerely appreciate you.

I’m interested in doing the Parentheses with the clipping options being ge/op/si on a three way switch. If I put a jumper wire in place of the LED(D4), and Ge Diodes in D3 and D5 would that work? Alternatively could I socket D3,D4, and D5 to leave open the possibility of using it in its original...

Already got the a100k✅. Thanks for the heads up on the C500k. I realized that’s actually what was in the kit I did as practice leading up to the build I’m doing currently. Glad you suggested that before I started this build. Got one in the mail now.

Thanks for this. Really cool to see the different versions lined up like that. Feeling like I definitely want to do a separate 250 build now. Definitely more variance from the D+ than I’d thought. I went D+ first due to my general preference for germanium clipping. Now I’m curious about how the...

I am preparing to build the Distortion 250. Planing to stick to the current build doc for a D+ style result. I plan to socket C1,C2, and C4 to experiment with cap value and type(for mojo). I’ve seen those are commonly changed in mods. I came across an old thread on here documenting a 250 Gray...

Thanks for the reply. I’d seen this but don’t have enough technical understanding to apply it. Does the cap affect Op Amps that are “internally compensated” or like the OP07 data sheet says “For most applications, external components are not required for offset nulling and frequency...

What effect does the 30p Cap in C6 have when a compensated Op Amp is being used? Specifically the OP07 and 741. Also wondering if it’s possible to damage the Op Amp this way(including if removed from LM308)?I built my Muroidea with a socket for the 30p, as I’d read you remove it with compensated...
