Duo 250 - Original caps (or not)?

[Juror22]

I was finally ready to recap my Duo 250 and when I opened it, the caps already appear to have been replaced!!
(either that or they did a really mediocre job of installing the original ones) I have plenty else to do if these are replacements. (recapping the screen is next).


Is there anyone with a picture of an original 'before' board's caps or that can just take a look and pass me an authoritative decision?

It’s been recapped - the original solder would have been much cleaner than that. They also replaced the cap at C36 (top of your picture) with a tantalum instead of the original electrolytic can.

Thanks mdeverhart! I suspected as much, but thank you for taking a look. I also checked out the MacDat site and there are apparently no caps that need to be handled on the LCD, so I am going to button this one back up (I replaced the Li battery some time back) and move on to my other Duo.

Still worth checking the inverter just in case. I have it marked that I don’t know whether the 250 inverter has any electrolytics or not.

If it was me, I’d be looking to tidy up that cap job, even if it was just using a bit of flux to improve the joints. The way they’re done, they could go dry.

That's an excellent idea - I totally overlooked the opportunity to re-recap! I was overly concerned with whether or not there would be leaking and totally missed that, thanks!
