Re: Thandar TG2001
Bit puzzled why you had trouble finding the LM317T, they are a very common adjustable regulator IC along with the the LM337T and aren't hard to obtain from reputable component suppliers eg Mouser or Digikey. It's possible you have a short circuit on the output of these regulated supplies and fitting a new one won't necessarily cure the problem.
Also not sure why R29-R30 would have burnt out, wouldn't the resistors around the main output attenuator be more likely to burn out if back fed from the Mosfet circuit you were testing, or were you using one the other outputs?
