Here's the current version of that part, still being manufactured: (Vishay Sprague 36DX 30000uf, 25VDC): https://www.alliedelec.com/product/vishay-specialty-capacitors/36dx303g025bc2a/70079382/
About $50.

I'm curious. Why do you think that the cap needs to be replaced?

Usually the big lamp supply filter capacitor doesn't need replacing. In fact I don't remember ever having to do that. The 5V and display power filters, yes. But never the big one.
Quoted from ChrisHibler:I'm curious. Why do you think that the cap needs to be replaced?
I like to favorite threads like this to find parts that are missing, especially when you buy a project pin. OP didn’t mention a replacement so I’m assuming it’s just gone.
Quoted from mrm_4:Hey man, I’m just dumping the info that’s out there as a repository for people to compare prices.

By all means that was no dig on you.
It was more of a being butt raped by marco.

haha I know man, just having some fun with ya
i literally just bought that one from G-P-E for my Firepower resto for 2 reasons:
1. Its Black
2. Its $12
The 40 year old original blue one is "probably" fine but now i don't even need to question it.
Edit: 3rd reason: its GPE
A couple more good options at Mouser Electronics (my favorite source for parts):
Lowest price, exact oem specs.:
https://www.mouser.com/ProductDetail/KEMET/ALS70A303DA025?qs=sGAEpiMZZMtZ1n0r9vR22YqjN7vGN3ZSFC7Ixb34xzWK9fCV4GllLQ%3D%3D
More expensive, but known to be high-quality (and in production at least 40 years):
https://www.mouser.com/ProductDetail/Cornell-Dubilier-CDE/CGS303U030V4C?qs=sGAEpiMZZMtZ1n0r9vR22bNos12dWCDWPsAPy5duZ7Q%3D
You can also use my Bridge Board to replace it.
It has the big capacitor split into two 15,000uF more common capacitors.
It also replaces the two bridge rectifiers and adds fuses to those lines.
Goto my website http://www.inkochnito.nl and click on the Bridge Board image to read more about it.
When the heck did Kemet start selling electrolytics?
As far as I remember - they specialized in ceramics, film and tantalums.
If mouser can sell them at $10 then surely I can do better. Just contacted them...
Cornell Dubilier used to be my preferred source for screw terminal caps. But when they raised the price from $3.50 to about $15 for one cap... that was it.
Thanks for all the replys. It doesn't need changing apparently,but I was looking for a possible replacement since all the boards have been changed and a new cap would top of all componites in the backbox. And also wasn't giving 55.00 for it unless it really did need changing. All this info is great,and Inkochnito is always cool to work with !

I was contemplating replacing this capacitor too just due to age. Maybe no need to? Mine isn't blue, it's silver and appears to have a date code of "7918." I'm guessing that is the 18th week of 1979.

For which game?
If it is an early Williams game I would recommend to use my Bridge Board.
That way you will also have added two fuses, replaced the bridge rectifiers and the big cap.
See post above....

Just replaced all the caps on my Space Station boards and was wondering if I should replace the big blue (or gray in my case) cap in there as well. Is it necessary? Was just doing some PM. I’m not even sure what it does exactly. Is it a filter cap coming right off the transformer? Space Station is an 11b, so already has the fuses before the rectifiers; so no bridge board needed (I did use it in my Space Shuttle though!)

Are you referring to the large cap mounted in the head? Is your game giving you problems now? Why do you suspect it needs to be replaced? Unless it is leaking or your game isn't running right there is probably no need to replace that one. I've never had to replace any yet.

Yes, the large one in the head. No specific issues fortunately. Was just doing PM and replaced all the caps on all the boards and was thinking whether I need to replace that large one or not. The only reason I suspect it needs to be replaced is just purely out of age. I work for a company that repairs industrial electronics and we always replace caps, especially old ones. These caps are almost 40 years old now. There’s no issues, and I’ve seen reports that it’s fairly expensive, so I think I will just leave it for now. Thanks.

Not necessary! That cap is for the control lights and that cap rarely ever goes bad.

This philosophy is counter to the better pinball rule, "if it ain't broke, don't fix it".
I've seen far too many board damaged by unqualified "techs" replacing perfectly working parts.
In general, I advise against it.
If you have the skill and experience, press on...but the "improvement" will be nearly zero.

Thank you! I figured that out and decided to leave that one.

I do it for a living and know what I'm doing. Replacing all caps is best practice and commonplace in industrial electronic repair and pinball electronics would be no different in that regard. Capacitors can drift in capacitance over time and still work, but that doesn't mean I should just let it lie so one day I have I have a shitload of crazy issues. That may be your philosophy, but not mine. Please keep comments like this to yourself.

Please sir. There is no need to be snarky.
I did say, if you have the skills press on.
Congratulations on being able to handle such jobs. You are in a small minority that have honed those skills.
We can agree to disagree, I hope.
Regards.

Thanks for all the work you have done for this community Chris. You have helped countless people.

Like this. I am sure you have seen plenty of boards similar to this. Unfortunately I do not have before images and this is part way through a repair.

I knew there were problems because there was a jumper from the positive of BR2 to the positive of C5 and I suspected that there was a problem with the negative of C11 although this missing through hole is not as critical (there is another path to ground). There was also a component side jumper to restore the zero cross circuit input. The "repair technician" that did this work really had his/her way with BR2. Just about everything you can do to destroy the circuit around it has been done.
DumbAss Yikes!
I always hate to see that kind of hackage.
But there is a sense of accomplishment by putting it all back right, at least as much as possible.
Langless28 Thank you for your kind comments.
