![]() "K5DH" wrote in message ... The mystery is solved! Thanks for the tips, suggestions, and lively discussion. Here's what I did to loosen the slugs: 1. denatured alcohol... no luck 2. non-acetone nail polish remover... no luck 3. acetone... yahoo!!! After sitting for a couple of minutes, the acetone loosened the sealer enough that I was able to break the slugs loose with a plastic alignment tool (I apparently pushed someone's buttons when I referred to that tool as a "diddle stick" in an earlier post!). First of all - congratulations on your success.. As to the "diddle stick" term, who cares.. it is only a term... For some one to get ticked, is ridiculous. It isn't like "you" came up with it. I've seen that term used hundreds of times. They need to get a life. Secondly, yes.. sets do need aligned often if components are replaced... maybe not much, but some... WHY??? For one reason because MAYBE the set was retuned to suit the failing component to start with and once it is replaced due to total failure, the coil is out of tune.... Could make a big difference. Whoever said they don't need tuned doesn't know their ass from a hole in the ground. They're either not good techs or too lazy to do a good job. The tuning "should" be checked. As to cores, I save cores from many items small and large.. I have probably 6 drawers full of various sized slugs for just such purposes. A lot of my repairs are from screw driver techs that break the slugs and cant get them out... OR the idiots they are, superglue them in place. Sometimes not able to get it out. I usually "carefully" drill it out and replace it. I've not had a problem yet. Not the greatest job to do, but with care, can be done. As for repairing old CB sets, a friend of mine got me started.. He likes the old sets and has bought a few for $5 and asked me to get them going, him buying the parts of course OR paying for them if I have them on stock. He helps me a lot, so I barter the labor and I also get a thrill out of the challenge. Not every defect is the same in cause or solution. Besides, the more you do, the better you get. As they say, practice makes perfect. Anyway, I have an old Lafayette Comstat 25A that was my moms and I acquired a Kris tube set also. Am going to get those two going. She also had a Johnson Messenger 250 Gold Anniversary radio I want to get working.... While I may sell the Kris when done, I won't sell the others.. as they are sentimental. One other thing, I often take those old radios since easier to repair... and use them to teach troubleshooting when I hold basic electronics classes or more advanced classes at our Amateur Radio Club. Most guys don't have the tools let alone the equipment to do the new stuff. So, they can learn on the older stuff. I troubleshoot it first, present them with the radio and a schematic and present the problems.. I then have them tell me their opinions of the causes. I correct them in their thoughts if need be... In other words, I don't let them go off stray into areas that would have nothing to do with the defect. I also give them hints on how to boil it down to blocks then to a specific area. So as not to end up chasing their tail and wasting their time. After I've gathered all of their opinions, I let them know who was correct or on the right path as I've already got the answers. I show them how I found it. I then replace the parts the next bench session and take it back to show the repairs.... We don't normally meet where we can do any repairs, so we just do show and tell.. and teaching in theory. But for me to trouble shoot ahead of time, lets me know the exact cause and therefore help them hone their skills down to a stage or part... That way, I too am not wondering what it could be, I already know. If we had more time and space to do actual repairs and had the equipment there without me hauling half of my workbench, then I'd let them troubleshoot with tools and equipment and replace parts as going along. But in the way it is now done, it at least gives them some understanding on how to proceed in a logical manner. C.L. |
