I'm trying to revive a Fluke 8600A that I got at the ASVARO swap. I got it working for a while, but I think that I may have zapped one or more of the JFETs in...
Reminder to the group, we're just a day away from the Musicians and DIY Electronics Swap Meet at 924 Gilman, Berkeley, CA. Sellers: We open for sellers'...
I've added comments to each one: http://www.flickr.com/photos/49451709@N00/sets/72157594481525349/ It was a great success and we thank everyone who came and...
To bad for me I missed it, stuck in Oklahoma City with the ice storm while attending training for my job. Would have much rathered been back home in the Bay. I...
Sorry to miss the swap guys, I couldn't get out of working. So I have a Rotosphere I got real cheap because it's not working. Seems to be the power supply....
It's okay to use a power supply that is rated for more amperage than the original. Before pulling the transformer, check the rectifier diodes (or 1-piece ...
... Sure, but note that it must be AC. Many wall warts are optimistically rated. Make sure the one you buy doesn't heat up too much. Basler is a pretty good...
... Think of the current specification as a MINIMUM requirement. Anything over that is gravy. The device will only draw as much current (amps) as it needs...
... D'oh! I can't believe I forgot voltage type. More important than polarity is the voltage type, AC or DC. Plugging an adaptor that puts out AC can damage...
... yes, as i understand it, a 1 amp, 12 volt powersup is a fine replacement for the 700ma, 12 volt supply. someone, pls correct me if i'm wrong, but i tend to...
Hello Anthony: Long shot here....sometimes these devices need AC to AC wall warts. Is your one of them? cheers - Richard BADIYEG@yahoogroups.com wrote: SF Bay...
OK, I've got a good 12vac 800ma power supply. Hook it up and the voltage off the supply drops to under 2v. Where's it going? Where else should I look? Caps...
Did a South Bay parts shopping trip last week and decided to check out <a href="http://www.excesssolutions.com/">Excess Solutions'</a> new location in...
One date that looks like it would work is August 19th, 2007. No other N.Cal electronics swaps that weekend that I know of, and it's between Mutant Fest and...
... The new location rocks, and is definitely more spacious. I'm glad they didn't have to move down to Gilroy (which is what the owner told me he might have...
... That's like 8 months away! Why not do it at least quarterly? Sometime in April or May perhaps? Late in the month so it doesn't conflict with either...
... You definitely can't count on any particular values being in the bin. I guess you could ask if they have what you want in the back. It would be polite to...
My GF teaches at a college in the Oakland hills. We were walking by a trashcan by some classrooms when I spied this board sticking out. I grabbed it. I posted...
Wow, great find. Good eyes. A 325-0-325 power transformer is perfect for a Fender Champ, Princeton, Deluxe, etc. Looks like it was part of a power supply...

I¹m jealous! Cool score. But is there any risk to grabbing such a circuit? I¹m a newbie here, trying to learn about amps (and learning rather quickly that...

Eric Miller that is. Eric answered my question about USB scopes with an offer of one of his older scopes for cheap. Of course, I took him up on it. He showed...
