After finishing a double Arachnid using the newer boards (with rotary switches, etc.) I figured I'd go back to an older Arachnid I haven't had time to box up.
I got this one a while back with the FV-1 pre-populated, but I'm getting no wet signal. Here's a rundown:
I got this one a while back with the FV-1 pre-populated, but I'm getting no wet signal. Here's a rundown:
- The mix and volume controls operate as expected (with is zero output when the mix is fully clockwise)
- The 78L33 measures fine and the FV-1 is getting 3.2v where needed (voltage readings match my other boards)
- I tested all the ICs (aside from the FV-1) in a different build and they all work fine
- The only change I made after populating the board was to replace the 220nf coupling caps with 1uf MLCC caps to get closer to the latest board revision (as per this thread)
- I've triple checked all component values and orientation as well as reflowed the solder joints
