Default Toroids on ebay - $25

Wanted to run this past you guys to see if there are any alarms:

120VAC primary, dual 24VCT secondaries, at 12A each

http://cgi.ebay.com/Toroidal-Power-T...trkparms=65:12|66:2|39:1|72:1240|293:1|294:50#ht_500wt_924

Seems like these would be well usable for some decently sized chipamp power supplies, no? If you guys didn't have any big red flags, I was thinking of ordering one or two. Thoughts?

Looks like a good deal. It should work great for an intermediate level bench power supply.

If you're looking for a fixed +-24v power supply at 12A per rail, you can get two of the following: http://www.mpja.com/prodinfo.asp?number=17429+PS . It would be $50, but it may end up cheaper once you consider the cost of additional components to make a complete power supply.

Amveco is a very reputable transformer manufacturer, but be leery of cheap 24+24VAC transformers used for cheap battery chargers. I've bought a couple just such cheap transformers, not from Amveco but from a cheap Chinese source, and their mechanical 60Hz noise was unacceptably loud. I mean, you could clearly hear the hum/buzz from 5-feet away. They sounded like you expect a cheap battery charger to sound like buzzing away in your garage.

Again, an Amveco part should be fine, but depending on the design requirements and specs they were built to (versus an off-the-shelf part), they might be a little less than ideal.
