Bad solder joints. There's a thread somewhere on here about that problem with some photos of which ones you'll want to freshen up.

Yeah they look like platinum, one is slightly yellowed. Also, one of them I sometimes need to smack a couple of times to get the crt on. Any ideas what the problem is? Just a loose…

Even more impressive is that you got two keyboards and two external hard drives!! Are they both platinum?

Well done! That's what I call a good trade!

haha outstanding!!!! now all you need to do is get over and pick you up a Floppy Emu/HD20 Emu and a 1meg Re-Writeable rom disk kit. http://www.bigmessowires.com/macintosh-floppy…

Indeed! Good job! c

Nice trade.

One more: what's the line filter capacitor voltage? It just says 47uF, I don't see a voltage. I am guessing it's 250V?

You can get a 20a max multimeter at harbor freight for a couple bucks, Mallet works good with portable battery packs as well !

More questions, and my $.02: My multimeter has a milliamps up to 200mA, so I might have to go get an extra analog one, plus it won't even give me mA reading on a battery. My multi…

Good luck with it! You will get them working again!
