1962/3 Zenith 27KC20Q

[Penthode]

Well, I have pulled the chassis to give it a clean. As I had expected, the plastic on the early convergence clover leaf is shot. The later Zeniths with the bright Red, Green, Blue enclosures seem to stand the test of time but not the earlier open plastic loops. Does anyone have or know where one could get a replacement?

I see that the later Zenith Roundie sets all have the same convergence coil resistances so this would do as a last resort.
Also, the control knobs have crumbled. The plastic seems to crumble on these early Zenith color sets. I'll post some photos. Otherwise the set appears to be in good shape.

I did however find a lot of sticky gunk on the wires. It doesn't necessarily look or smell like a nicotine set. It looks more as if it is cooking grease. (I wonder if the set was in or near a kitchen?) The consistency is thick and it isn't soluble in water: it seems to dissolve with paint thinner. I'll post some photos of this. Any thoughts?
