I have been working on a model 116b for the last few months and up to now thing have been going well. It have finished the recapping process and have had the radio playing. The chassis was as dirty as any I have seen. Covered in a black oily sooty substance that is very hard to remove. I scrubed and cleaned using 409 cleaner and was able to get most of the grime off. I let the unit sit for a couple of days to dry and when I turned it on everything seemed ok in fact the shadowmeter that had not worked before now did. I came back to the project the next day and when I powered up the radio I had lots of popping and crackling from the speaker and smoke from the band switch area, also the 2000ohm resistor in the shadowmeter circut was so hot it began to smoke. The radio does still get weak reception but still lots of smoke and an occasional spark from the contacts on the band switch. I did try to dry the unit in the oven to no avail. The resistor is number 75 in the schematic. The shadowmeter no longer works. I was hoping some one could give me some suggestions on where to go from here. I received lots of help from members of the forum on last years project which was a 201x. It turned out great. Thanks, Gary
