Hi Guys,
I am trying to fire up an old Deckel FP5NC before hopefully finding it a new home, and I am having an issue with it letting the smoke out of a resistor on (what I think is the) 5vdc power supply board. I have replaced it once, with a 100 ohm resistor as it appears to be indicated as in the book I have for it, but just as soon as I flip the switch, it smokes it again. Everything I can find says it wants 380 to the machine, which I managed to get almost exactly with a multitap transformer and some buck/boosts.
I don't *think* that it has the option to be setup for 208/240, but if I am wrong, PLEASE let me know! Also, there's no way that having the phase rotation backwards can do that, is there? And lastly, I have 3 hot wires and a ground in my shop. I tied the neutral to the ground in the machine where the wires come in. I get 220 between L2 and the neutral, so I am good there, correct?
Does anyone have any ideas on this guy? Such a sweet old machine, I really want to see it go on the live in someone's shop as a bragging piece, and not end up as parts or something...
I have pictures of the offender, as far as I can tell that's the only thing keeping it from being alive, if I just knew why it keeps frying...

EDIT:
Upon hunting, I have found that Rider-83 had this exact problem back in 2006, and replaced r29 (the one that has been smoking) and C11 (which upon further inspection looks like it could be bad as well)... I am going to swap them both out and try it again, but I would sure be interested if anyone has any idea why they might be burning out, or if it could just be a getting old thing?
