Could we get a schematic/layout for the Powersound Overdriver?

Unfortunately, they all got mixed up so not sure which was which but some from Tayda, some from Jameco, and some from Amazon. Some of the older ones were from Tayda too so it might be chip by chip. Again - another reason to build a test circuit. I also got some of the newer SMD versions and PCB...

Not really a question but I have a strong tip/recommendation for anyone trying to build any circuit that uses LM13700N ICs (ie many phasers). Build the CDXL Reissue Envelope Filter first and use it as a test circuit! Previously I struggled in getting an AionFX Redshift/Whetstone phaser to...

OK, follow up. I think I might have to just ditch this build :( I tried replacing R4, R5, R6 with normal-size 4K7 resistors and still no dice. Its really strange, the signal is completely clear At IC1, pin 7 and to one side of R4. The other side of R4 is distorted. I tried swapping out IC1 as...

OK. Finally had time to pick this back up. Thoroughly reflowed the board, cleaned the back. Still the same deal. I tried swapping ICs, no dice. I removed that resistor (r4) and tested it and it is 4.7K and replaced it. Same. One interesting thing I noticed is that when I tested voltages the...

Hey Yall! Been busy at my normal job so my "night job" of building pedals and posting them has taken a hit. Thanks to all the helpful comments here and just a steady diet of building and debugging I will say that I've gotten so much better at diagnosing problems. In this case, I have my first...

OK! It works! I took the suggestion and wore gloves and had my hands in my pockets (I work in a kitchen during the day so no shortage of gloves). I probed and while 9V was going to D1 and C2 it didn't seem to be making it out. I probed around further and for some reason (probably a bad joint)...

OK! I realized my power supply is low amperage so going to test tonight with a higher one. Also, I'm a little uncomfortable but I think I can probe voltages later, too. Will report back. Thanks!!

I finally got all the parts I needed for my build. Put it together today, carefully plugged it in and nada. Bypass works, but no LEDs, no sound when engaged. I tested continuity around the power section and seemed ok? I'm nervous to test voltages. Any ideas? The LEDs should still work whether...

Very excited to do my first tube build soon! Any tips on sourcing good EF86? I saw that amplifiedparts has a bunch of different ones, any specifically recommended? Or should I go the eBay route? Thanks!!

Ok! Took a break from this but after dealing with some charge pump issues on a different circuit I came back. After studying the schematic it looked like the big problem was that pin 3 on the pump was not ground. I took the socket out and replaced it and viola! Ground and the pump worked. Now I...

Don't have space for a full-blown oscilloscope on my bench currently, but I was wondering if anyone has used any MacOS apps for this purpose? I mainly want to test some LFO circuits I've been playing with.

Hello! I thought I'd start back with a relatively easy build but this one has me stumped! I have a sunflower fuzz that works fine for bypass but no sound when engaged. At first I thought it might be the transistors or the bias, but when I tried probing with my multimeter I realized I seem to be...

Hey Everyone! It's been kind of a while as I had to pack up all my things and move. Finally set up in my new "lab" and having fun. Built a couple things the past two weeks but nothing finished except for this beautiful new friend. This is my first time using a pedalpcb faceplate and it looks...

Oh that's a really cool idea. My 3D design skills are still rudimentary but that seems doable! backlit panel would be possible if you had some other clear material in between the plate and the enclosure.

In the process of moving all my gear but happy to print some faceplates for those who want them

(sorry I'm totally bombarding the builds as I'm about to move and packing up all my gear for a little while ...) This was a super fun build! I bought a bunch of germanium sets the last time small bear had a sale including a Tone Bender matched set and so I was craving building a simple classic...

A lot of folks on here mentioned how the Hydra is the most fun/best delay around these parts and watching the TPS show about Echorecs I couldn't resist. Not much to say about the actual build. I took the advice from @JamieJ's build and used an A100K for the mix and clipped pin 3. Works great...

Definitely looking forward to ordering one!

No, its 8.8V and 0.95V
