oof, those screws are expensive.
Thanks for the link though.
Last night I took the cleaned-up chassis and started
mapping out the caps.
All the caps pulled. The previous owner told me he did a cap replacement within the last 5 years, but that was only
half true. He replaced maybe 6 caps, but the rest were stock!
AND those caps he replaced were cheap low-end ones like Jamicon and Elna.
Here's the mapping. Sorry I didn't sort the list on the right by number, should have done that...oh well.
I found 2 damaged pads when I desoldered those caps. I for sure didn't damage them, as you can see one of them looks like a cold joint, but that's just 'cause that one side of the pad is gone. The previous owner must of torched them. Continuity still checks out, but they're hanging on by a thread! I might have to jump these connections for
peace-of-mind.
Another annoyance is there's a whole lot of silicone glue/paste holding caps down. Some of the glue is holding caps that have no business needing to be held, like the bigger 100uF caps that have thick legs and solder. Those things ain't going anywhere, no point in gluing them down.
It's like someone spunked all over this chassis.
I haven't nailed down what variant of the MS8-26 this is, because there are a lot of information out there that isn't clear. There are a few known variants, MS8-26A, 26SU, 26SG, and 26SE?
I
speculated that I have the 26SG due to the monitor model sheet inside the cabinet, but I wasn't 100% sure. When cabs changes hands in it's history, you never know what was left stock and what was replaced. So I wanted to varify what monitor chassis this actually is.
After talking to Peter from arcadepartsandrepair.com he sent me a cap list of his kit for the 26SG. I compared it to the caps I pulled from the chassis and neckboard and noticed there are some differences:
2 of the caps are at different values, and 1 of the caps is missing on my chassis.
I am not sure if the previous owner just put in the incorrect values on those caps that don't match, but what's weird is that my chassis is
missing a C579. The serial numbers on my chassis and the neckboard both match what arcadepartsandrepair have
listed on their 26SG kit page. So I'm confused as to why these 3 caps are not consistent with that cap kit list.
Anyone have any information you can share so I can lock down this variant? I'm waiting to hear back from Peter at arcadepartsandrepair. Hope he might know what's up. It's so weird.
Later today I'm going to tackle touch-up paint on the monitor bezel.
This train keeps rollin'!
