I've been running this Maggie nearly every day for an hour or so. I've gathered a list of caps to replace, and have some of them ordered as of 7/30/10. The audio problems are gone. The tuner slugs are working now with some paper strips installed to keep the slugs from slipping. At some point, I need to do something about this tuner. The plastic parts of it seem to be rotting away. Someone 'cleaned' the tuner with something that looks like it melted the plastic surfaces.
I've got it running thru my Dish Network satellite on channel 9 for now. This channel tuner slug seems to be in the best shape, and holds the fine tuning fairly well. The picture looks nice, and the set has good contrast and brightness. When I take a pic with my camera, it clips the image and makes it look like I have big vertical size issues, which I dont.
I've replaced both tuner tubes, now, along with all 3 IF tubes. The vertical oscillator tube is testing better on the twin diodes now than it did when I started, and the linearity has improved. The voltage doubler capacitors are among the first to replace, even though things seem to be running fairly normally. More to come.
