Monday, Oct. 19, 2015, 12:20 a.m. — I have been doing more cleaning in the shack this evening, but as you might expect, no Beugler yet.
But I did spend some time working with the Hallicrafters HA-5 VFO, and determined that the fuse holder hacked into the power line is just that — it was placed in the line that originally went to a terminal strip on its way to the primary side of the power transformer. Right now the fuse holder is broken loose from the terminal strip; whoever soldered it in place wasn’t exactly neat; there’s a wire with melted insulation from sloppy use of a soldering iron, and there was solder splashed on the chassis and a couple of cables.
I’m trying to think if I have an old piece of equipment that I can take a chassis fuse holder from; there’s room to drill a hole in the back of the chassis and it would be a lot better than floating a fuse holder with exposed clips between the chassis and the case.
I’ve been doing some research on the Heathkit SB-102 LMO and the belts I need to replace. Shouldn’t be too tough a deal to complete, but I’m seriously thinking of purchasing a copy of the assembly manual.
There’s a guy on YouTube who has one of the best set of restoration videos I’ve seen so far on his SB-110 6-meter rig. The techniques he uses apply to any vintage rig. I’m seriously considering doing as he did — taking the rig chassis out and washing it all down with a brush and dish detergent. It’s amazing what it did for the SB-110 he worked on. After washing and rinsing, he put it in the oven at 150 degrees for several hours to dry it out.
I think I will plan on replacing the electrolytics in the rig just for good measure, and then bring it up on my variac slowly to reform the caps (or try to). Ultimately, I want to purchase a replacement PC board for the power supply that replaces the four big filter caps, but that’s to come, I’ve got other things I need to finish first.
