So I got to know what your favorite tube color TV set is? : D
Don't have a particular favorite, just like to contemplate the steady improvement over the years, and at a continually dropping real price. But it's also impressive to think about how much was accomplished in tube sets, before it was possible to throw hundreds or thousands or billions of active devices into a product using semiconductors.

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.
