RE: [CAD_CAM_EDM_DRO] POWER SUPPLIES

The aforementioned $60 supply was at www.herbach.com. If you want to
roll your own, www.mpja.com has a 24v 10a transformer for $18. I didn't
see any suitable capacitors on their site. Ordered mine from
www.mouser.com for $20. Rectifier also came from mouser, about $4. All
in all, buying a $60 supply is a bargain. I priced a 24v 10a switcher
from (somewhere), and it was over $300.00. Everything is relative.

Regards,
JJ
