Is this PSU worth even saving?

So I started recapping this Hitachi (I think) PSU for my SE project and as you can see there is some bad corrosion from leaky caps. I don't THINK there's any trace damage but some heavy solder mask dage in spots and just 91% iso isn't taking off all the harder black areas.

I accidentally bought caps for an Astec PSU and I don't know if it's worth returning them to console5 or I'll end up losing money still to get the correct ones for this PSU.

IN SUMMARY: is this worth saving? I don't own any solder mask and would have to order it and I'm unsure how far the damage is. Previous owner powered it up to post pics on eBay and then it shut off on him part of the way through.

Since I already have caps for an Astec PSU should I just source one of those? Which of the SE PSU models are best anyway? And how can I identify the brand from the outside if I can't see the PCB?

Wow! That looks more battery bombed than cap affected. If my brother told me what the eBay seller told you and I saw that, I'm not sure I would believe it. I'm not disputing you, but what you were told and /or shown. I'm just suspicious of the location, pattern and look of the damage and identifying the cause correctly is important to correcting it.

Next step IMO would be to treat it like battery damage (or severe cap damage) since either presents as alkali involvement and you will want to bathe the affected area (briefly) in vinegar, then rinse with DI water. If you let it sit too long, vinegar can cause its own damage to the board. There are guides online for soaking items with similar damage, if you need tutorials. UV or heat cured solder mask is available on eBay and Amazon (I used some of the UV stuff on some smaller cap repair areas, just a few days ago - make sure you have a safe UV source). Depending on how much work you want to put into it, it looks like the damage could be repairable, but your mileage may vary.

Make the decision on what you feel you can handle. As for the caps kit, if you cannot work something out with Console5 (I would at least ask - they have been fantastic to work with in my experience), someone here might be willing to buy it off you for their recap.

Thank you for the reply! I think it'll probably end up being more trouble than it's worth because I have a pretty limited skill and I'd hate to think I had everything repaired and sink a bunch of money and time into it only to find out that it's still having issues. I found a Sony PSU with analog board, which gives me a backup flyback at least and a backup entire analog board, for 55 bucks listed as tested & working so I'll pick it up.
