Thanks- I was wondering about a power supply issue, so was looking for one to avoid tracing those tracks around the relay etc, however when I plugged it in last night it worked fine! Visually inspecting the pcb shows no signs of burnt ICs, and all the off board wiring seems sound! Pots look/sound fine and work in all positions, so I have no idea what could’ve caused the issue!

Thanks for the help anyway!

Where are you based? I’ve not had a chance to pop the lid off yet.

It’s only lack of a scope (and an accurate schematic) that’s stopping me from trying to fix it myself- I was an engineer at Laney, but with no scope I’m not sure how much diagnostics I can do!

I was wondering if it’s the regulator (or a buffer stage), depending on how the power LED is wired…

Thanks
