well next up will be the filter caps. but you know they seem be working fine, but I know they should go. I figure the inline fuse would protect against a short, and if they open no harm will be done, just problems. I will prob do them just to be safe.

I am getting excited about building a box for it. May have to invest in a table saw next. She is gonna love that idea

I am gonna be out in the garage till late tonight, after rockford hitcock, then night gallery.

I can't see that focus diode tube light up, granted its 2v but it does not seem to be getting very warm I did not check the filaments yet, have to check the schematic to see what feeds the heaters

ok after an hour or rockford I see how the convergence is acting up.

it seems to be out of alignment on the lower part of the screen by vertically (on vertical lines you see red green blue side by side. on the top part of the screen the vertical looks good but the colors are displaced horz (colors are separated and stacked on top of each other on horz lines).

sorry if I am not using the right terminology.

So I guess convergence can be out both directions on different parts of the screen? in my case the upper and the lower.

I am going to spend some time tomorrow with the service manual. Looks like you could need to go to school to learn this stuff, or at least apprentice for a long while.

Wow, You done good and the picture looks great.
Try cleaning all the controls on the convergence board. Check and re solder the pins and ground connections. Also you may need to replace the selenium diodes. It is not as hard as it looks. {See picture}

great looking picture.the linearity could be the resistor on the control.it goes bad all the time causing a vertical problem.if you were closer,i have 3 cabinets that i need to move out.there are in reasonable condition.i think the 15 and 16s produce the best roundie picture.those crts are really spot on.congrats on this.you couldnt have gotten a better one for a first time.
