I wish the ARRL would put out a book on how to make capacitors and re-winding transformers, etc. Some parts are impossible to find at reasonable cost. It is too bad to dispose of gear that can be repaired. I have re-wound an Atwater-Kent radio power AC transformer early in my ham radio career. I would have liked to know how to do that right the first time. I know faulty capacitors can ruin transformers. Older gear should be more repairable than solid-state parts that are no longer made for one reason or the other. I would think one could make vacuum tubes if one knew how to go about it. |

A quick search of the QST archives produced a good article on rewinding transformers.. And, I think the subject is covered in some older ARRL Hanbooks. What type of capacitor do you want to build? 73, Larry, KQ4B |

Most of the parts that one could build probably wouldn't require an entire book to build, but I'd love to see a few newer articles on the subject. I used the Periodicals index and tried the following searches: winding transformers construction homebrew capacitor There was at least one article on building a variable capacitor, but you'll have to scroll down a bit. Homebrewing some components would be a real challenge. In a variable capacitor, very minor vibration would translate to a change in capacitance, which would make for a very shaky variable-frequency oscillator, for example. 73, Ed Hare, W1RFI ARRL Lab Technical forum moderator |

You may also try Lindsay books. Lindsay often has "old technology" books like the one you wish for. They are on the web, I forgot the address, but they offer reprints of books from "way back". Many are about making old style radio parts-- including vacuum tubes! |
