SF2 cab update
<< < (2/4) > >>

Wow, lucky dog!  I've been trying to find some plans for a SFII cab, or even better yet, an original to gut for my first attempt at a MAME cab, and you happened to find one locally for $40...

If you have a capacitance meter, check the caps on the PSU's main board and make sure you don't have any dead ones. Following that, if you have an IC Identifier, check that it reports the main power transistors properly.

Check all of the solder connections on the board and re-flow the solder on all of the pins. More often than not this will fix a lot of problems without doing anything else. Most of the monitor and PSU faults I fix fall into this catagory. I quite often do this before I even think about doing anything else.

If all of the above checks out, then you have a short circuit somewhere.... It's certainly a PSU Fault.

A at worst case a new PSU is very cheap.... about $40 USD at most. £25 GBP. Which makes it pointless repairing it if there are a lot of parts in a faulty condition.

The sticker you found in the bottom of the cab is a Wells & Gardner Monitor Part Number for a 19" K series monitor. It's possible that your cab has had a monitor change at some point.

I was thinking of just ordering a PS. I have no real test equipment other than a meter so checking all else is a no go. So are you sing it is not a WG?

Thanks
Andy

If your monitor says "Phillips" on it then I'll guess that was on the tube.....

It probably means you have a W&G Monitor Chassis using a Phillips Tube. That's quite common. Hantarex use Phillips tubes as well.

I'd guess you probably do have the original WG monitor, but monitors are easy to swap out if they have problems, so you never know. If you want to know for sure, compare against diagrams in the manual for the K7000 series of monitors. Here's a quick link:

If it were me I'd definitely replace the power supply. They're fairly cheap and you won't have to keep worrying about it.
