Hello everyone,
Hoping to get some insight on how best to go about overhauling this old Ibanez delay. Its from 1983 so it celebrates its 40th birthday this year, the unit still functions however i heard a high pitch oscillating whine from it a few weeks ago and decided to strip the chassis and have a look.
It looks like the 25v and 16v caps are leaking, there have been a few replacement caps in its lifetime as it has some bi-polar caps installed that differ from the polarized ones in the unit.
My plan was to swap out all of the electrolytic capacitors, i was planning to use 105c Nichicon HZ or similar the power side and use 85c Nichicon MUSE bipolar caps at the control/digital side.
There's also 3 capacitors im having trouble identifying, two of them look like white tantalum capacitors and there's one with a blue plastic casing over it? They look quite tired so i thought i might as well swap them while im at it.
I have a college degree in vehicle mechanics so i have experience with electronics repair and ive done some surface mount stuff before but this is a bit more labour intensive compared to what ive done in the past.
Any additional input or advice would be appreciated.
