model 16 code 125
#5

OK, this set has 7 electrolytic caps in it, which I replaced. None of the original cans on top of the chassis (there are 3 cans) are the originals, and the one which contained a bank of 4 caps was replaced with one that only contains 2 caps, while the other two were mounted underneath the chassis. None of the values were even close to what the schematic calls for (the 2 mfd was replaced with a 20 mfd!) So I carefully replaced them and was going to slowly bring the set up on my variac to see if I could coax some sound from it. I felt confident enough that the crude bank of caps and resistors used to replace the missing driver transformer must've worked at one point and would at least help me determine if there are any signs of life in the set.

Well...at 60 volts on the variac I was already drawing 5 amps, followed quickly by a steady trickle of smoke rising from under the chassis. Not good. I quickly unplugged it. I checked the transformer and it's still where it should be, so I don't believe that was the culprit. So, having made no other changes other than the electrolytics, can anyone verify for me where the main electrolytics (#91 and #98 on the sch) are connected? I just want another pair for more skilled eyes to check out the schematic for me, as I keep thinking perhaps I inadvertently put one in with the polarity reversed. Thanks.
