All fixed up! Zenith 20Y1C48 lookin good!!

This is the set that carmine had that we were attempting to fix a while back over the net. I went up to detroit area last weekend and traded him a set for this one. Luckily the set was a simple fix. Turns out it had a shorted vertical output tube. That wasnt enough though, had a shorted cap in the vertical section causing the pincusion circuit to seriously effect the picture. the UHF tuner needed to be rebuilt and aligned too.
The horizontal output was arcing internally, so I put in a new 6LF6, adjusted the slug and brought the current down to 183ma!!! The fly runs as cool as if it were not even on! An extensive convergnece procedure brought the picture to a razor sharp focus, and focus is centered on the pot nice and sharp. All in all, this set has an outstanding picture and this is one of my most liked zenith cabinet styles for 1968.
