I have a kit working almost perfectly, but have had endless issues with getting the mux boards to work, and also the regulators are getting warm quickly. I've looked everywhere for shorts but no luck. All voices work, sequencer / display and all seq functions work, all indiv and bus outputs work, etc. Just need to fix the mux board (to get accents) and the regulator heat issue.

Is there someone based in the US who could take a look and try to get these final issues resolved?

Thanks!

Did you measure your power transformer voltage output ? It could just be that it gives higher voltage that warm the regulators up quickly.

where are you based? post photos of the mux boards

Transformer voltage is OK.

I'm based in Oregon, and I've attached some photos of the mux boards.
