Roland SH-5

This SH-5 came in with LFO-2 not providing modulation, and the led was dark, also the bender action was jumpy. The LFO-2 issue was due to a  bad CA1458 operational amp which was replaced and restored operation. The bender is metal on this unit and we were seeing a little grittiness due to wear and lack of lubrication. I stripped out the keyboard control panel and cleaned, lubricated (pot cleaned and a small amount of grease applied to metalwork), and aligned it. Tuning and scaling was a little off on both oscillators, and was adjusted to spec.
