Re: Ibanez Delay Rack Re-Cap

Thanks for that info, the marking does indeed look like a letter Z, its a bit easier to see in real life so if you can see a Z in the photo then i would agree with that.

Would you say that replacing the power side with polarized Nichicon caps and doing the rest with bi-polar Nichicon caps would be ok? I would prefer bi-polar caps to minimize user error on my side, there's only a handful of caps on the power side so I would just keep those polarized.

The pots are just dime sized varying between 10k and 500k, linear or log depending...

Re: Ibanez Delay Rack Re-Cap

I managed to photograph the polystyrene film cap to try better identify it. The markings have worn off so i bumped the contrast and sharpness to try see it better....

Thanks for your reply,

The idea behind replacing all caps is purely because they are 40 years old at this stage, the bigger ones haven't vented or bulged excessively but the red residue at the bottom of them doesn't look like a good sign.

As you mentioned, it looks like someone has painted the tops of the smaller caps to differentiate between them, colours used are white, red and blue. The bigger cap values are as follows,

1000uf 25v x 2
1000uf 16v x 1
100uf 25v x 3

Then various smaller...

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,...

Hello everyone,

Just joined from the UK, looking for some advice replacing the electrolytic capacitors in some old rack mount effects.

I have a degree in vehicle mechanic's but im no electrical engineer, just needing some pointers to try overhaul these old unit's.

Cheers!
