Cleaning up an attempted cap-change on a Fever SOS pcb.
Wondering if someone with the pcb could help me out, it would be much appreciated.
First, what is the value on the film-cap at place "C44"?
Then I would need Cap-values (mF and volt) on all caps to see if they are correct?

Still need to confirm values on a Fever SOS board.
(Monstermugs was a Dangun Feveron board.)

Sound section looks identical to me so MMs values will be fine.

Yes, another member will also confirm.
Some of the caps on there now are wrong.

Thanks Some-mist.
Yours also looks like it has some changed caps?
Interesting is C34 and C32 that is 470mF on yours and mine but 1000mF on a Dangun board.
(And all three big caps are 1000mF on a JP Esprade that has an identical sound section.)
Edit:
Are you sure about these two? (Values looks kinda strange.)
C41 = 2uf 5v
C39 = 10uf 6v

Possibly prior to me owning it, but nothings been changed since I've had it. I actually don't even remember where I got the board since I don't have feedback or pms for it on here/ng/ao. Was trying to figure that out a few months ago.

Thanks for the C44 value, have ordered some.
And will prolly put 1000mF on all three big caps.

Actually I am starting to believe that there are no "Fever SOS" or "Dangun feveron" specific pcb....
Mine looks like the Fever SOS scan at world of arcades but was bought in Japan as Dangun feveron.
Some-mists board looks exactly (same small yellow caps, green film caps.).) like a Dangun feveron board on Ebay.
...and regarding the three large electrolytic caps I see all kinds of variations.

I'll double check as soon as I get home (won't be until late tonight
), but that's how it read. I'll try and snap some close up pics.

And fixed !
Changed all caps, changed pot and changed the damaged poly-cap.
Now looks clean and works perfectly.
Big thanks to Monstermug and Some-Mist, I owe you a beer .

You should list the proper list of caps here in case someone else needs it.

There are some variations between the boards, so there is no definite list.
But a list that works and covers most cases that I have seen is this one:
(Though check your board in what is installed originally.)
C52 = 470uf 16v
C57 = 47uf 25v
C56 = 47uf 25v
C40 = 22uf 16v
C30 = 100uf 25v
C27 = 100uf 25v
C45 = 22uf 16v
C39 = 10uf 35v
C29 = 1000uf 16v
C34 = 1000uf 16v
C32 = 1000uf 16v
C2 = 47uF 16v
