Sometimes in this hobby, one can become a little complacent. Over-confidence can lead to bad conclusions. When you don't check things out correctly, and assume prematurely that you know what you're doing, you can waste hours tracking an issue that just won't reveal itself. This is what happened to me here. I could have edited out that wild goose chat, but instead left all the video in so that you can witness personally how convincing I can be, even when I'm wrong :) Hope you enjoy the video.

Here's a link to one of the best circuit descriptions on a tube radio, from start to finish, made by some people who really know what they're talking about. It's a 5-part series, starting with the link below: https://www.radiomuseum.org/forum/grundig_grundig_schematic_diagram_analysis.html
