TT or Mega STe power supply question

[Randy]

got a bad one on my mega STe, but I have two supplies that came with a TT, both have the same umbilicals as the Mega STe, one on the metal mount and one not mounted, but I can use the metal mount from the old PSU.  It does turn on but I inadvertently smoked a resistor R19, there was a center mounting stud that shorted out R19 and started it smoking.  This supply is a Skynet Electronics PSU white/clear board, trying to find out the value of the smoked resistor, any one know it or how to find out?  Thanks

Thanks Robson, that is the schematic for the Phiphong, which I also have but is really not working very well at all, pulsing output and a sparking noise to boot!  The Skynet is pretty close to working all right except there is a -10.61 vdc instead of -12 volts, trying to figure if I can fix that section as all the rest work fine, a schematic of that circuit would really be helpful!

I see, sorry about the confusion. Unfortunately both my PSUs here are the Phiphong ones, so can't check the value for you. I let you know if I find anything useful.

One other thing, I can replace the power supply with a meanwell RB-65B, same outputs and ratings and almost the same size.  However, the meanwell does not have the "PG" connection which I believe is needed to turn on the computer, any ideas on how to get that out of a meanwell?
