Tube Radio Schematics Heaven.
thousands of Tube Radio Schematics online, for free.

Yikes. Radiomuseum. A waist of my time and my money. Definitely not recommended. Make good note, the site is not for free at all. You pay with your time and your energy. Member fee is high for how little you get for it. Sooner than you think, your "points" are gone, and you are forced to upload things before you know it. Otherwise your acces gets limited. Then all the struggle and trouble was for nothing. Very arrogant reaction when I asked for support, as their uploading site did not work. Support, what support?! They write me: We have only a "help" file, and that is all. If you don't find what you need, we don't help you personally. I say ok, give me my money back. Their Answer: No, not after downloading 12 schematics. Now this was really stupid of them, because I have over 100's of thousands of documents and I can upload almost anything somebody needs. But no, they refuse to set me up when the upload doesn't work. Either find it out yourself they say, of forget it. I saved all those arrogant emails of them. It's the typical reaction in the internet, when somebody thinks you can't do anything against it. Well, but I post my opinion here. That I can do against it. So... here it is!
