Edit: I do have a favorite color TV tube circuit, and that's the RCA X-Z demodulator and matrix circuit. The matrix circuit includes a sneaky DC restoration effect with the horizontal blanking pulse, which is essential for preventing the gray scale tracking from drifting with either demodulator section drift or scene content changes, yet no RCA or other service publication ever explained it fully.

Indeed, it already impressed me that we accomplished color tv as early as we did. now that I have been learning more about it, its even more impressive! Up until HDTV this set of mine has an amazing picture that's about just as good picture as a newer CRT tv's ive had.

Now that's interesting, I wonder if they even fully understood what was going on then? hehehe
