thousands of Tube Radio Schematics online, for free.

Radiomuseum Warning! Make good note, the site is not for free at all. You pay with your time and your energy. Member fee is high for what you are offered. At first you think: It works! Now I don't need to look at those cropped pictures any more. But happyness lasts not long. Sooner than you think, your "points" are gone, and you get warnings to upload things, for more "points", or your access will be restricted. Already after downloading 12 schematics, I was a restricted member. Now look, I was prepared to upload documents, but the upload software was not working. A very arrogant reaction came, when I asked the owner, Ernst Eib, for support. This man seems to have an Ego problem. He writes me: We have only a "help" file. If you don't find what you need, we will not help you by email or phone. I say ok, then give me my money back. His answer: No, not after downloading 12 schematics. (from other members). Now this was really stupid of him, because I have over 100.000's of schematics, I can give him a few thousand. But no, he refuses to help me, as a matter of principle. Unbelievable. He really writes me: Find it out yourself, of forget it. I saved all those arrogant emails of him. It may be a typical reaction in the internet, when somebody knows you can't do anything against it. Well, but I post my opinion here. That I CAN do against it. So... here it is!. Here I found a link from somebody with similar experience with Mr. Ernst Eib.

For the solution, do this: Print the figure one, cut the pieces out with scissor, and then lay them on the second picture. You will be amazed that it works! Sill, when I did so myself, this lead me to the answer.
