Roland Jupiter4 and Promars MRS-2 Replacement Power Supply

This is a plug-and-play drop in replacement for your Jupiter4 or Promars synth.

Switch mode modules run cooler and you can shave a couple pounds in weight by losing the stock transformer and linear reg board.

Headers for all stock wiring harnesses, just bring the post-switch line and neutral wires to the terminal block and you're good to go!

Units are built to order, so allow us a few days to build and ship!
