Roland JV-30 Repair

Don’t let old technologies die just because they are old. D. Scott Williamson found a garage sale buy of an early General Midi rompler in non-working order and diagnosed it with almost no knowledge of the board. A cracked SMD (‘surface mount device’) and a shorted diode diagnosed via a heat seeking camera, and done. Scott even decided to print up new slider caps.

The JV-30 makes an AMAZING controller and I used mine as a front end to a Peavy SP/SX rack mount sampler (designed by friend of the site Scott Peer), until it was replaced by a Kurzweil K2000…surprisingly deep if you could get your hands on a SYSEX editor and identify all the non-registered parameters not listed in the programming manual, as well as a second unlisted ROM set that allowed for backward capability to older Roland rompers.
