Hello folks,

     If this is the PT 1000 chassis,very interested about this one, have the Bush version where the 5v chopper (FSD200) blew it's top, caps drooled down the board killing the 24v supply. Have now got 5v S/by and 24v supply going, but just a pulsing input into IC37 (12v Opto) but no output from IC37 and all normal start-up supplies and no shorts around IC30 (ICE1QS01) or the secondary side. Supply will not fire up.
 
   Thanks Chris Steele.
