Poly 61 Innards

Must get a better way of attaching the battery to the board...

Time to dig out the soldering iron...

My Roland MKS70 has been getting temperamental lately - keeps cutting out after a few minutes, at one point it only worked by leaving it on it's side! I reckon there's going to be some cracked solder joints in there somewhere causing the problem. Time to dig out the magnifying lens and the solder iron.
