Midi Matrix Rack Schematic & Mains Voltage

[UltraBitchin]

Hi everyone! I am now a proud owner of a vintage MIDI Matrix Rack unit from the 90’s and an Abacus. The MIDI Matrix came from Japan and says “wired for 100v” on the outside. I’m in the USA and want to wire it for 120v.

I haven’t been able to locate a schematic anywhere. Does anyone have one or could anyone potentially help me with a mains swap? I’m handy with a soldering iron and feel comfortable doing clean work.

That is cool! I’ve never seen one of these in the real world.

I don’t know if John still works at the Mesa Hollywood store, but he used to be the only guy that was able to repair the Triaxis. He might be able to help you out.
