Looks like it has some good stuff in it that I'm interested in
learning about. Is it worth the 20 bucks? If not, any other good reads? Patrick |

news ![]() Looks like it has some good stuff in it that I'm interested in learning about. Is it worth the 20 bucks? If not, any other good reads? Hi Patrick. It covers basic repair information for those with no technical background. If all you want to do is tinker in your own radios and pass the difficult jobs to a real tech, then it will do fine. If you want to really get into repairs and mods, you should look for a book that covers at least basic electronics and radio theory. With the theory, you can work out the rest. The trained monkey approach may be fine if you are just tinkering with your own equipment and can only hurt yourself, but it really helps to understand more of why things are as they are so that you don't do repairs or mods that seem OK but can cause serious problems. It should always be remembered that high voltages can kill, so mains sets and tube amps can be dangerous. Basic safety needs to be learned if you want to look at any such equipment. One fine example was a repair I once saw, where the complaint was that it was "not getting out well". The strange thing was that it was putting out about 7 Watts, but not getting as far as a 4 Watt radio. The problem was a modification inside that caused it to spread it's output across not only the CB band, but also Amateur frequencies. I am sure that the "rig doctor" involved saw no reason why his circuit should not be used... it seemed to work. Basic theory would have told him what would happen.

Been there done that. I used to work for a local computer repair shop here in Columbus Ohio and one day I happen to be replacing a deflection board (as I had done many times before) in a Apple 19" monitor and I forgot to discharge the CRT before unplugging it. I believe my heart stopped beating for a few seconds. Needless to say from that day forward, I always remembered to discharge the CRT tube.

It's so easy to forget or overlook something, everyone makes mistakes. This is why it is always best not to work alone on high voltage electronics or electrics. That extra person could save your life, as long as all the engineers know life saving techniques. I think you will find that Lou Franklin now offers free PDF downloads of some of his books from his site. You could also take a look at my two sites below. Both are purely information sites, all for free. Regards, Peter. http://www.citizensband.radiouk.com/ http://www.electronics.radiouk.com/ |
