I found an old Tehnoton Gloria 4 radio receiver in the attic. I want to restore it, but the printed circuit board diagram has faded badly. I’m especially interested in how to properly connect the antenna and tune the frequency filters. I tried reading old radio repair magazines, but they only give general advice. Sometimes there’s a faint sound when I turn it on, but I’d really like to figure out the exact issue.

Has anyone already saved the Gloria4 manual or schematic? How do you usually find old manuals for rare equipment? Are there any forums or archives where such manuals are posted? Would anyone be willing to share a working PDF? Where can I actually download the complete schematic for the Tehnoton Gloria4 radio?

I’ve never understood why people keep old appliances. To be honest, I can’t really help you solve this problem. I can give you a link to a website that has schematics and instructions for various appliances. Based on the name you gave, I found the user manual for Tehnoton Gloria4 radio . It might not be the exact model you’re looking for, so you can try searching for the right one using a search engine. I used this site when we moved and had to reconnect all our appliances. As it turned out, I didn’t know anything about it at all. There are no subscriptions or paid downloads on this site. But there are clear diagrams.
