Spent this whole weekend doing a combination of things- a little woodworking to get closer to finishing a decorative shadow box for the ground breaking shovel at work, and Tim did some circuit tracing on the chassis. He started at the tuner and worked through the IF strip, at the end of the day he got as far as the first video amp tube (6AG7). Next weekend we will be getting close to the demod and CPA sections, so I'm hoping by then that we will finally be able to get a feel for how this set operates. Circuit tracing is labor intensive though, many breaks are required to avoid getting burned out and to avoid making mistakes. Right now, everything is on paper. When he is finished, it will be drawn out with MS Paint or a schematic program so it's easier to read. One thing is clear: it will be a very large schematic indeed. We both had the idea of breaking this up into sections: tuner/IF, luma channel, chroma, matrix, and finally deflection. That should make it easier to understand.
