Greetings, I've been restoring a Harvey Wells TBS-50. Finally powered it up this weekend with the intent of using it on 80 meter AM. I got no power out. Zero....
After looking at other TBS-50 pictures on the web, I've determined that someone has replaced the 80/40 meter tank coil with a coil with many more turns. And no 40 meter tap. Strangely enough, I have great drive to the 807 grid on the right frequency. Does anyone have a TBS-50 that's a parts donor? With an intact tank coil for 80/40 meters? Any leads on a replacement part appreciated.... Or, I can modify this coil to reduce the turn count, but it's a very close spaced coil. I have a good grid dip meter, but in checking other bands with it I find that none of the tank coils resonate in any ham band, which is probably a flaw in my test setup or lack of understanding of how this tank should work....I get a strong dip at ~2.1 MHz in the 80 meter band switch position, which makes me believe someone started a conversion to 160 meters. If you've got some experience in this, I'd appreciate a tip on the best way to get it back in shape. Thanks.
