Started off the day with a little drama. First time to build something with a PS. Not so successful yet. Initially had the primaries wired incorrectly in the wiring block (neutral to red/black primary, hot to red/black primary). No LEDs on the PS and eventually I figured it out (after being saved by some fuses).
I powered up after correcting (I hope) my first blunder. When I powered it up the LEDs lit and so did the bleeder resistors. For some reason I used 4.7 ohm instead of the 2.2 ohm. They both smoked....quickly.
Is this the only problem you see?? Did I hose the PS supply board up when I screwed up the transformer primaries. I initially shorted the AC and tripped both fuses in an effort to "fix" the AC to transformer folly. Do you guys see anything blaring? I did not electrically isolate the bridge rectifiers with Keratherm.
Even with the pre 4th fireworks, this is fun. we'll see if I can avoid killing myself.
Thanks for any much needed assistance,
Jeff
