CS50 Power Supply wiring question - ACK!


 

So i was stupid i admit and maybe didn't take the precautions i needed to - in doing a power supply rebuild i only took macro documentary pics and not an 'overall' - but i THINK i got all the wires right - it would be heartbraking after having spent the last few months rebuilding this power supply to blow it up when turning it on again to test it ...


so the question is ... "do i have the two longer orange wires you see in the foreground going to the right places?" - there are two possibilities only ... either as they are now or the reverse order??"? (note the splices in the wires)


I checked clues like the printing on the wiring but both run in the same direction and are cut at the same place on the printing sequence ... (ugh) ... i've gone through the schematic several times and i'm just not confident enough about it ...though think i may have it right ... the leftmost orange wire comes from the collector of the 2SD234 and the one to the right comes from the 2SA745.


 

alright i got it figured out now - thanks anyway ...

though now I've hooked it up to the wall via an incandescent bulb to test for any faults and there's NOTHING happening - bulb won't even come on ... I have it OUT of the synth and I have the sense lines hooked up properly ... is there any reason that i wouldn't be able to get voltages out of it being hooked up to AC power alone? in vitro as it were?? I thought i'd be able to ... though when i measure the dc resistance across that prongs of the AC cable - I get an open circuit ... I suppose that's NOT a good sign? or??


anyone??
