I'll see about unplugging the IF lead and check for a rebuilt Fluke or borrow my brother's. Will still get one, but don't want to wait any longer than necessary to get this puppy up and running. The safety caps will be here Tuesday. Thanks

Is there any danger of a short if I accidentally touch any other lead on the G2 pot or the body of it? Thanks

You could slip & put 800-900 V where it doesnt belong so use a clip lead to play it safe. Slip happens when working in dark, awkward conditions. When doing it for a living you just measure away for the sake of speed but you can relax & take your time. Less mistakes that way. BTW when working on its side the purity will usualy be bad, just ignore it. 73 Zeno |

Okay, got the safety caps in and double checked I didn't mess something up while cleaning. Made sure I didn't dislodge any transistors or cause any two or more leads to touch each other. All was well upon start up.
I used clip on leads on the center post of the G2 pots (that's the lead to the CRT socket). I measured each G2 to be between 426 with pot down and 752 with pot up. So I'm assuming those numbers are good. Next...as I'm typing the set is warming up so I can try the grayscale again. Hopefully I can get the red raster line this time. Wish me luck.

Well I managed to get a dim red raster line and adjusted the blue and green to the same level (really the best I could guess as a dim line looks like a dim line). From there I got a b&w image and adjusted the taps to a screen that had just a very slight blue tint to it. Moving the tap lower made the screen a bit red. So I put it back. Should I try moving the blue G2 down a bit?
The convergence is a bit messed up. I'll have to wait until Thursday when I get the pattern generator. I'll use it to converge the center dot, then do a purity and finally do a convergence. Hopefully all will go well. I do have a question about picture height and width. On my other CC2 it has height and width adjustments. On this one I don't see them and they aren't listed in the SM. The overscan is a bit too much and I'd like to reduce in all directions. Thanks.

I got my hands on a Minwax mahogany stain scratch cover up stick. As long as you don't get too close or shine a light directly on the surface, you'll hardly notice if at all. My next step is to get all the off white color cards from Lowes and see if I can find a white the matches close enough. Can't exactly take the set to them for color matching.

The set is making itself at home.

Maybe I missed it but whats the chassis ## ?
IIRC the vert controls are on the module with little extention shafts. If there is a large adjustment needed UNLESS the pot has a bad spot or someone messed with it it HAS a problem. You should do the vert next, it may cause more damage. BTW your voltages are OK, its not unusual to tweek the grey scale a little especialy an old set. Be sure when doing your doing the final set-up the set has run a few hours & is nice & warm. 73 Zeno |

I got this set from someone that got it from a shop of sorts. It looks like they messed with things as I just noticed the deflection yoke clamp wasn't tightened down.

I'll looked over the SM again and found that on the vertical board there are two pots. One for size and one for linearity. Not sure what the second one does. Is it important to adjust that one while adjusting the size pot? I didn't find a horizontal size adjustment.
