northcountrybob Posted November 13, 2023 Share Posted November 13, 2023 Not sure if anyone is keen on this but I thought I'd drop a post in here... I've been playing around at laying out some PCB's and wondered if anyone might like one to play with, or if anyone has any suggestions. The green PCB I laid out for miniMELF parts and a through hole LM4250. The parts sizes on this board are a bit mixed and it's not the best layout I've done. I have a version where I dropped an SMD SOIC8 opamp onto this layout in place of the through hole footprint. The board will be 25x35mm. The red PCB is pretty much the same circuit, but has a SOT-23-5 footprint for an opamp. 25x24mm. I have a version of this with C7 as a smaller part, an extra pad for a second pickup, and all the relief holes removed, which is about 25x18mm. I haven't proven they work yet and don't have final BOMs. I want to play around with some different opamps on these. My plan is to jam one into a Player Jazz Bass. It's just the classic 2 band stingray EQ. I cross referenced the schematic that's all over the interweb with my own Stingray Classic. Just wondered if anyone might find one handy for a project? 5 Quote Link to comment Share on other sites More sharing options...
northcountrybob Posted November 23, 2023 Author Share Posted November 23, 2023 Made a real small version. Soldering 0603 parts by hand isn't something I've done for a while. hopefully it works.... 🤞 4 Quote Link to comment Share on other sites More sharing options...
