I guess I'll know tomorrow when I ground it and remove it.

the larger brown one off it. Usually they have a small phillips clamping the wires down. Thats IF it has 2 holes ! The 103-193 came in at least 2 styles. Fat grey ones & later plain old black. Dont worry about them unless they have been changed. Grounds I assume you checked the terminal strip grounds. When u attack the jail bars. I think you have a generator. Hook it up & if it has a staircase pattern ( stripes going from white to black across the screen) look at the video with the scope. You will see two lines of a staircase. This shows you how the levels relate to the pattern. Go to the IF output ( point 38 or C1 on Sams) first at 7875 cycles & you will see 2 lines of the pix complete with staircases at apx 1.5 V. This is raw unblanked video sync & all. Next put the generator on blank raster. If the bars have been introduced at that point you will see 10 little bumps, if not nothing but a line between the horz pulses. Work your way to the right Q203 B, Q203 C, Q204 B, Q204 E, etc until you see them. The pattern will get bigger & be blanked but you will see two lines. One other thing. Odds are this set ran for years with too much HV. Check the ABL that is off the tripler at R362. CR223, R359, 360, Q201 etc. While you are at it get an old book or look on internet for what the things on the scope are. Sync pulses, burst, back porch, blacker than black etc. It will help you a lot. 73 fer now Zeno |

The wire was just press fit into the anode cap. I'm attaching a couple pics of the wire removed and the cap. There was no crimping or set screw. The farther you insert the wire, the tighter it gets.

My generator doesn't have the stairs, but I have been wanting to get a newer one. Any suggestions on an inexpensive, but decent one? The ABL you mentioned I'll take a look. I do have a new Q201 and can get an NOS CR223 (Zener Diode) if need be.

When all these problems are fixed, I'm putting this fiber optic sign proudly over the set. Right now it's hanging from the ceiling.

From Zeno's post;
"first at 7875 cycles & you will see 2 lines of the pix complete with staircases at apx 1.5 V. This is raw unblanked video sync & all. Next put the generator on blank raster. If the bars have been introduced at that point you will see 10 little bumps, if not nothing but a line between the horz pulses.. Work your way to the right Q203 B, Q203 C, Q204 B, Q204 E, etc until you see them. The pattern will get bigger & be blanked but you will see two lines." Your best bet, starting fresh as you are, is to look at these items as he stated, but your bars will be easier to spot as he said with blank raster however you get it. But pay attention to the stairs, or whatever you have, then go to blank, and you will see the part of the trace that makes up the tv picture, the bars will be in that space. Can you upload that schematic to some free ftp spot and post a link to it, then just delete it after those interested in this thread get a copy....?

Would this generator work for what I need to do? It seems to also have a horizontal output, so I think that might help with the scoping?

& a good guaranty. Read this from Sencore. http://www.broadcaststore.com/pdf/mo...20-%204053.pdf Nice sign, had the same one at shop in white. Owner scooped it up, I grabbed a Chromacolor II wall banner & some other Zenith relics. Sure wish I took the parts stock, bin after bin of NOS Zenith. All in dump now BTW DONT put that scope on the boost or HOT collector unless it has a 1KV probe. If you like to see fire trucks try it. 73 Zeno |

All that generator is missing is a button labeled "automatically fix my tv"
Very nice pdf from Sencore about the ntsc signal..... Everyone should have it.....
