seems the caps are fine, full voltage quickly, no heat, so I plugged in all the tubes and will hook up the crt/yoke/convergence bd tonight for a full power up. I will monitor the B+ current still.
will do this all later today, will post the results later. wish me luck...

since I had the sams resistance tables I started check some, on the vert tube I had an odd reading on of the pins, noticed it was the vert hold, no big its just the position of the pot, move the pot and I get wild swings. check the pot and indeed it must be very dirty, so will clean up the pot before powering it up. I am just a bit paranoid about that vertical circuit

I would think some spray in all of the pots would be in order.
Those resistance tables are sweet when it comes to tracking down resistors that may be out of spec. There are, many times, readings that may seems off and actually only be due to a setting of one of the controls.

copy that charlie, sprayed and looking good. checked about 1/2 the tubes, so far very good. I did spray the 4 pots up front. I was a bit nervous about getting into the pots on the back. guess I could note the position and spray work them and get back to that starting position.

IT WORKS!!
I am going to have to touch up the linearity and there is a slight convergence problem (are they related) on the bottom, but it is coming along. I snapped a couple shots before even playing with the tint/color, so it looks better than this now. Last edited by DaveWM; 03-18-2013 at 12:04 PM.

oh and my B+ current looked good 440ma Sams calls for 460
 gonna knock back a cool soda pop, grab some grub, and see if I can clean up the linearity a bit. Gonna need some one to talk me thru the convergence, I have the manual but would rather talk about it 1st. Thanks for the encourgement and help, esp Charlie for letting my yack on forever.

I will have to get some more pics, it is looking a LOT better.
I think I will add a .5 amp in line fuse to the B+ just for that extra bit of safety. I had a neighbor over, he is technically inclined, I think I may have set the hook in him.. He remembers this stuff like I do a kids from the 60's

here is another, still getting better, you can see all the color guns seem to be working fine. oh and the linearity adj got rid of the odd lines on the bottom

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
