This is my current project, although I haven't touched it in two days due to yardwork and other errands needing attention. It is a Zenith model 5758, with the 24MC32 chassis. It was a set I pulled from the TV shop several weeks ago. This set looks extremely identical to the 5040/29JC20 I am in search of. As far as the looks go, the only differences are the legs are placed inward under the cabinet instead right on the corners, and this one has the UHF tuner. The 5040 was only VHF.
So far, I've only pulled the chassis and gave it a bath in the driveway. It was hurtin' for one! Looking the chassis over, I couldn't visually find anything that failed. Maybe that means the picture tube is no good.
Perhaps not, but that thought crossed my mind. I don't have a crt tester, so I will have to find out the hard way... get the chassis up and going and then plug it in!
The cabinet is in semi-decent shape. The top is hurting pretty bad, and I will probably have to cover it with a new piece of veneer. The rest of it is ok, but once the top is fixed, I'll refinish the whole thing.
I'm not sure how far I will get with this... I return to the ship in a week and I will have other things to do that will take up my time. Hopefully, I'll get far enough to completely power it with the CRT plugged in and have some sort of picture. The rest of it will have to wait till I return from the ship again.
