I’ve read comments here about my write up for the past year and a half or so. I’m happy it’s helping folks out. Lol it seems like it’s becoming the unofficial procedure. I actually haven’t used my low tide in a good while. I’m trying to record a lofi track and I’m going to be putting the mix...

Actually, after revisiting, and after playing through my vibrobot for a while I saw that it was still distorted in sine wave mode. I looked more into it and I saw that R21 (91K) was enough out of tolerance to cause distortion. I replaced it with a 100K trimpot with one leg removed, making it a...

Hello. I don’t know if it’s too late to post on this thread but I just went through the exact same thing on my vibrobot build I just completed. Perhaps I can provide some insight. I had a nasty distortion that I could not dial out at any position of the trimpot. I traced my signal and found...

Feel free to reach out if you have any trouble.

Ok, new update. I ordered a new pcb and started over. I was 100% sure all my values were correct per the documentation. I also made sure to use sockets instead of soldering IC's directly to the board in case I needed to replace one or more with no risk to damaging the PCB. I got very different...

Hi. It does appear that it’s backwards. During my troubleshooting, I accidentally pulled my surface mounted Q1 and destroyed the pads. I ended up substituting another sk series transistor; I twisted the gate and source legs to go into the proper pads making it appear backwards. Q1 is actually...

Hi. I recently put my Low Tide modulator and I'm having some pretty nasty trouble with it. I'm unable to get a proper wet signal. I have set the bias point of the V3207 BBD to a healthy 2.5V (1/2 of the 5V going to the VDD terminal). At this bias point I should get something on the output but I...

Is there a recommended gain and volume setting at which we bias the transistors?

Ok. So I just finished putting everything together and there’s some things I’m unsure about since there’s no documentation available. I assume the trimpots are for biasing the J201 transistors? Since there’s a TC1044 in the circuit, I take it that VDD=18V and the bias voltage for the...

Great. Thank you

Hi. I just got my Argentum 1212 pcb. There’s no documentation available but it seems like a straightforward build. Is there a drill template for this pcb or is it the same as a different pcb on one the site which has documentation available?

Hello, I just built my low tide mini. I dialed in the gate and bias controls as best I could. The bbd is biased just until the point where it doesn’t distort anymore. I dialed in the gate until the point where it gets dark with the gate control all the way to the left. I noticed that the...
