Vintage Synth Repair

John is not kidding, some of these older synths did not make it even that
long with some of the lower
quality electrolytics. A good example, the Casio DH-100, while not something
you call a vintage synth, it
failed mainly due to the cheap off the wall electrolytic.

NO REASON not to replace electrolytics, IN THE REAL WORLD. Even if the
machine has been operating at relatively low temperatures (under 45 C) they
are way past their life expectancy. Particularly in the case of Japanese
electronics of this vintage. The capacitors used where not of the best
quality from that era. That's the real world.

Panasonics actually have a relatively high variation in values and lower
tolerances to temperature and life expectancy. That also is a real world
assessment.
