Older ARRL Handbooks

That's the real trick, isn't it? ;-) And if you can't find old magazines, you can get QST on CDROM, so a volume of that from the right time period would supply plenty of projects. Of course, most of the projects in the Handbook came from QST to begin with, so it's not like you miss much in the project department. Cool, I'll have to look into it. Of course, a lot of TV sets were AC/DC, so the filament voltages are all over the map since you'd put them in series to run directly off the AC line. Unless they start with "6" or "12" the tubes may not be so useful. You're right, the voltages range anywhere from 3 to 33 volts. Two of them are 6V6 tubes, so I have some hope there. Most of them are miniatures, and some of them have the numbers missing, which makes things really interesting. Ralph |
