The metal top on the second IF coil (455 side) was rusted away. This is the piece that pushes down over the coil form and the slug threads through it. Thanks od of the coil form is .3 inches. This was a very common part in old tv's and radios so maybe someone can yank old from an old coil on the junk pile.

I picked up and SX 42 today and am about to start on it. Is that the same coil that is in the SX 43? If so I have a parts unit on the way and you will be welcome to one. Mine is pretty much original with only parts replacement for minimal repairs as it aged. Pictures I have seen show all the paper caps as brown, wax covered types that I have seen all my life. This radio has bright yellow Mallory "Plascaps" in it rather than the old style. That sure threw me for a loop when I took it out of the case. I wonder if anyone knows about them? Are they "plastic" covered paper? I sure would like to avoid replacing all of them if possible. What I lack is the cover that fits over the variable tuning capacitors. I hope someone has one that will share. While not to difficult to replicate, it is a fer piece to the nearest shop that can do that. So like Chris, I am begging.

They appear in the 1951 Allied catalog so were available by then. In general, Mallory made very high quality capacitors. If they are original they probably need to be replaced.

I can see how it was made, there were openings for the trimmer capacitors and the coils in that area. With some doing, I can duplicate something should the need arise. I am fortunate with this set, my measurements say that the majority of the resistors are in tolerance. I found that almost amazing given its age. I lack three X1Y2 capacitors and have replaced the multi-section capacitor with a new one. I hope to have those ceramic caps this afternoon then I am going to try to power it. Do you have other suggestions before I do? The paper caps were all replaced some years back and the ones I have removed and tested check good. Since the audio transformer is missing, I plan to use my audio wattmeter and plug it into the phone jack for testing. If it works then I will consider having the audio transformer rewound. I wonder if you know if that transformer was a weak link? I noticed this one has a 1/2 amp fuse in the HV center tap, probably put there after the transformer went. All the sites that cover restoration have had the transformer replaced. 73, Jim W5JO From: Greg Gore Jim, Yes, there is supposed to be a zinc plated cover over that area.

I have three issues that advice could help. 1) In the fm alignment the 105 mc alignment peaks just as it should, no problem. When I go to 60 mc I can't even find the signal anywhere on the dial much less trying to peak it. Any suggestions on where to look? 2) I had to re-string the tuning and it almost works. But in tuning across the dial the 2 1/2 turns on the tuning knob capstan wants to overlap itself. I have to back up a bit and the overlap cures itself and I can go ahead again. Any thoughts on this problem? 3) My glass dial is "flaky" but I see a new one may be available soon (but costly). In advance, thanks for comments and help. Skip Magnuson W7WGM Spokane, WA
