Well, spent a couple nights recapping the underside of the chassis. Nice easy access to most of them. 2 of them required demounting the horiz osc. transformer and shifting it aside.
Only strangeness found concerns C139 and 140. Service data showed C139 as .035 /600V. What I pulled out was .035/1000V. Replaced with a .033/2kV.
Data showed C140 as 0.1/1000V. Installed cap was 0.1/600V. Replaced with a 1kV unit.
Also replaced R197, a 10K 10W wirewound. Tested OK, but was pretty cracked and flaky looking.
A 5AXP4 arrived on my doorstep today, just in time.
Installed it and fired the set up-- first light at about 7:30 this evening!
Had a badly defocused horizontal line at first, but playing around with height centering and linearity pots got a sort of squished raster. Had some static from speaker, and flashes on the screen when changing channels. Tweaked things a bit to get a decent sized raster on the 5" tube.
Hooked up my VA62 to the antenna input and fed in a crosshatch on channel 3. Couldn't get anything there, but channel 4 seemed to come in somewhat. Tuner needs a serious cleaning, but I was able to get a signal through it.
Vertical and horizontal sync were both way off, but fiddling with lock and frequency trimmers got a recognizable pattern on the screen. Audio comes in OK, but slightly mistracking with video.
Vert linearity pretty bad and sync very touchy, so will start checking resistor values in the vertical circuits. Will need to get into the tuner for some cleaning. Multiburst pattern only shows resolution up to 3.5 MHz, so may need to go through an IF alignment eventually.
All in all, a nice bit of progress for 2 days. Time to plot strategy from here...
