That thing is gorgeous! Excellent save! I've never seen a white one, only the black with gold trim.

The cabinet was made by Zenith, they made two different chinese cabinets for their early color televisions that I know of, one was this white one with the designs on the front, the other a black one with just the gold striping on the edges.

I pulled the chassis. The guy I got it from said that he was using it as a daily watcher for the past few years, until the breaker started going off when the tv warmed up, and this is when he decided to sell it. So the first thing I did was to check the diodes, they were good. Then the 160mfd electrolytics, not so good. I think I'm going to just replace all the electrolytics. I swapped the bumblebee caps out with orange drops this afternoon.(There were actually quite a few in this set - I wasn't expecting them in this late model of a set) I'll replace the electrolytics in a few days.

This is a real 100% Zenith produced at the factory. Zenith contracted with Drexel furniture for the cabinet, but it was all put together at the Chicago plant.

Back then we were not worried about leaky caps. Also Zenith was not replacing transformers either! It was a well designed chassis albeit obsolete for the day. Zenith would not spend the money to "modernize" their assembly line which made an expensively built chassis.

Those transformers do get pretty hot, especially after watching the set all day like I do sometimes.

Oh yes... You burn your hand if you try to carry the chassis by the transformer after the set's been running. Same with CTC-16s et al. Those transformers hold in heat like a Thermos bottle!

Not sure, but I do know they had a bad reputation for failed field coils in the prewar radios, since the field coil was also the input choke for the power supply. Any load, such as a leaky filter, would overheat and open the field coil. Shoulda put a fuse! Charles

That was the way the chassis was when I got it.
I recapped the electrolytics and checked all the tubes. All the tubes were good, and except for the damper they were all original. I would guess this was a very low hour set. The guy I got it from said he had it shipped out to CA from Kansas a few years ago. It probably saw more use in those few years he used it as a daily watcher than it did when it was new. pics of the chassis after I cleaned it up and recapped: http://www.audiokarma.org/gallery/sh...&size=big&cat= http://www.audiokarma.org/gallery/sh...&size=big&cat= Last edited by Adam; 04-20-2009 at 04:06 PM.
