As for the lateral magnet, on these early sets, they are actually supposed to be at about 2 o'clock position like its shown. If you were to move the lateral magnet to the top like most other sets, you would notice that it would move the blue lines vertically as opposed to laterally. you can see the blue pole piece through the neck at the 2 oclock, just center the magnet over it.

The 26KC20 is zenith's 3rd generation TV chassis. Ive actually got one in a metal woodgrain cabinet like yours. I dont think anyone on the forum has or has ever seen a 27KC20, which is the next chassis after the 29JC20.

As for the "cateracts" on the 21FBP22, its very typical. There is a rubber gasket between the CRT and the lens. You will have to pull the CRT out of the set like you would expect and the lens will simply spearate from the CRT once you remove the mounting bezel assembly. The rubber gasket breaks down and will be very oily. You will notice a pool of oil between the glass and the lens at the bottom of the CRT when you pull it apart. There will probably also be some oily residue inside the cabinet beneath the CRT. The cateract appearnce is oil vapor residue. It cleans off really easy. I clean the gasket, which in my experiences have always been very flexible and not dry rotted with alchohol to dry the gasket of the oily fim and remove the residue. soap and water really doesnt do it too well. Good luck with it!

Thanks for the tip on the lateral magnet, I'm just used to seeing it at the top. Ditto on the oily residue in the bottom of the cabinet. Hopefully I can get to work on these sets soon, I have 6 roundies to restore now and no time to do it, but a little done at a time is better than nothing. This one shouldn't take too long as it should only need a good cleaning and a recap. I am trying to decide which sets to do first. This one might be done soon, right after my current project which is still that Admiral roundie. That thing is taking forever, the cabinet is still nasty and I will more than likely need a CRT or rebuild the one it has at Hawkeye. That set has about a million hours on it! I am also going to replace most or all the higher voltage resistors in the power supply as well as the rest of the mylar caps and the 'lytics, I've already put about 40 caps in it so far. It's got a lot of bad ones. This set WILL work if it's the last thing I do!! I just recieved the NOS Thordarson FBT the other day. I will be putting that in Friday since we are working half days on Fri. and 9 hour days the rest of the week. The middle of the summer will be nice, we work 4 10 hour days with Fri. off. That is when I will get caught up. It's hard with having all these damn "responsibilities", I give a good 'ol Archie Bunker raspberry to those! Oh and thanks for the compliments guys, they always make my day!
