Does Best Electronics sell OEM capacitors?

[ACML]

I've looked online at Best and they have I.C.s and diodes, but don't see any capacitors listed. Does Brad carry the old OEM capacitors for re-sale?  I know new modern caps are the way to go, just curious. In particular, looking for the big 10,000uF cap in the 1200XL (C060603).

asking Brad would be the thing to do. I don't know how shelf stable such a cap was or is. Capacitors like to be used every so often. Look up reforming capacitors and get some ideas.

I suspect NOS 35 year old caps would probably be dried out and fail pretty quickly.

I doubt it, but why in the world would someone want to purchase such a thing? There are just some things that there is absolutely no good reason to order vintage parts for, and capacitors would be at the very top of that list. Not only are there no good reasons to do so, there are many good reasons not to.

 

Here in the states, Digi-Key is your friend.

You also need to know the lead spacing of your old capacitor. It wouldn't hurt if you also overrated the capacitor by going up to 25V. This one might work if the lead spacing is 7.5mm https://www.digikey.com/en/products/detail/rubycon/25PX10000MEFC18X35-5/3134179

As a modern capacitor is likely to be smaller than the original you could do what the Chinese do with audio grade caps 🙈

The spacing of the OEM (ELNA) 10,000uF is 13.5mm.  I bought a modern replacement (2020 CKEM manufacture) and its' lead spacing is only 7.5-8mm.   See photos.

 

Shouldn't this be a good replacement?

Assuming the pre-install, non-cut leads are sufficiently long enough, the spacing really shouldn't matter all that much. You should be able to shape the leads as necessary to make a proper fit, then solder in place. Assuming that it fits, and electrical specs are the same or better, you should have no issues using any modern capacitor.

The original has 3 leads it seems, the third is for stability. That must be why the lead spacing is so large. The replacement can be made to fit by shaping the wires and will work as intended.

Digi-Key p/n 493-1093-ND - 10,000ufd @ 35v. Lead spacing is .5", same as Atari.

Nice!  I just ordered three.  They have essentially the same dimensions as the OEM.  This should pop (solder) right in nice a neat with 12.5mm spacing, rather than trying to fit the smaller one with 7.5mm spacing.

I agree with you, but I've also seen a handful of non-experts claim that modern capacitors are less durable or have worse performance than vintage caps. As far as I can tell, this is just audiophile-grade superstition.

My thought has always been that electrolytics are designed with a finite life span regardless. But that caps made 30 years ago do seem to have held up a heck of a lot better vs those made during the cap-apocalypse of the 90s. So I would hope that modern replacements today will hold up as long as those from 30+ years ago have held up.

Like all things, certain manufacturers are better than others. It isn't the age of bad botched stolen formula caps anymore though.

Brad sells resistors, diodes, and caps by the roll, if you want.
