Cab PSU: Cheapest crap from NZ (as often)

Post by Arcade-Projects »

Not a technical guide nor any question here, just a simple rant for the love of it.

My one and only cabinet is a Neo Geo Big Red Pacific version as seen there (bottom of the page- Allied Leisure 6 Slot):
hardmvs.fr/xml/pacific/pacCabs.php

That thing was made for the Oceanian market, which means the cheapest in every aspect:
- Kortek Chassis
- Zenith monitor (25", not bad but poor image quality)
- No name sticks (feel horrible) and buttons (you better have strong fingers)
- No name PSU
- Etc.

I've already done a lot on that cab:
- fixed the faulty MV-6F slot (only two slots working when I got it)
- fixed the MV-ELA board used to drive marquee lights
- replaced one EL panel for one the marquees
- built the missing memory card harness
- replaced the missing stereo headphone jack for P2
- replaced a couple of broken buttons and reordered them to follow the Neo Geo standard (A = red, B = yellow, C = green, D = blue)
- fixed both credit counters
- replaced the faulty bulb in the SELECT button
- recapped the chassis (which improved the image a lot but still not great)

Now I thought it was time to recap the PSU too cause +12V rail was much instable.
I pulled it from the cab and found it has no brand whatsoever printed on the outside, no serial, no nothing...

Once opened I learned the brand was actually Eago and surprisingly they still exist as of today:

I also discovered few really shocking things:

Image
Parts only have numbers to be identified on the silkscreen, no prefix at all (C for capacitors, R for resistors, etc.).
Some parts don't even have a number!

Image
Black dot (if present...) on the silkscreen indicates the positive side (+) on polarized capacitors!!!

Image
Values on capacitors are in MFD (motherf***er to Death? Mega Farad of Devil?) and WV (WagenVolks? Wrong Volt?).
