Today the 4 condensers I ordered from Hayseed Hamfest finally arrived. They were mailed on the 16th. There was a tracking number, but after it left their local post office there were no more scans of it along the way until it arrived today, then other scans magically appeared. I think the USPS was playing CYA.
I had to go to Morristown today for my eye treatment for macular degeneration. When I got back I began to replace the original electrolytic condenser cans. Much to my chagrin I found that the ones from Hayseed Hamfest were just a HAIR too big to fit through the hole in the chassis, and three of the four barely fit into the original clamp, the fourth didn't fit at all. I checked the specifications I sent them, which were exactly what is listed in the bill of materials in the Scott manual. They made them with a diameter just a little too big. The original spec for the three was 1 3/8" diameter, in other words 1.375", these were between 1.450 and 1.5" Fortunately I was able to fit these into the original clamp, with the clamping screw hanging on by about 3 threads, and keeping them raised a hair from the chassis top was able to use them. The terminals cleared OK. The fourth one was similarly over the specified size, but was so much bigger that it could not fit in the clamp, so I didn't use it. Instead I mounted a 20MFD 450V condenser on a 3 terminal strip, and screwed it under the chassis using one of the original screws that held the clamp.
Once all the condensers were installed there was nothing left to do but try the radio out. I hooked it up, and it works very well. I am able to pick up a LOT of stations on just my test antenna at my workbench. I still have a little more to do, clean the band switch contacts and other contacts but the radio actually works very well. So, here are pictures of today's work...
