A good friend of mine really came through last week. He spotted a Portacolor on the side of the road and nabbed it for me.

This is a pretty early model. It has neon illuminated tuning, color, and tint controls. The chassis was dead on power up, which turned out to be a damper tube with an open filament. The El-menco ceramic caps, including the .1 1000V boost cap were leaking wax like crazy, so I replaced those before I did anything else. I popped in a new 12AX3 and cleaned the tuner, and it came to life. All the can caps are running nice and cool. It produces a decent picture, but the focus is pretty soft, and this set doesn't have a focus control. Did early Portacolors have a focus rectifier that went bad? If so, where is it located? Also, how hard is adjusting the purity on these sets? Thanks in advance.
