What I've lost is my mind.
So for those of you who are just panting for the latest update, here 'tis.
Messing around last night. Looked for cracked solder joints but didn't see any. 'Course my eyes ain't what they used to be, so who knows?
Then I started rocking the tubes around in their little sockets. Not much happened until I got to the (ahem) "Chroma Sync Phase Det/Color Killer Det". No more scrolling stripes on the screen! I had Red! I had Blue! I had Green!
Not all at the same time, mind you. Seems I had my choice of a picture that was completely red OR blue OR green. Yeah, it's color, but not quite what I was aiming for.
Where to go from here? Wellsir, figuring that I couldn't make matters any worse, I yanked out all the tubes on the chroma board and reseated them. I noticed that the pins were somewhat corroded.
Okay, no more solid-color screen, but not much color either, so I went through the process of (I don't know what it's called) turning down all the screen controls, flipping the service switch on and turning the controls back up intil I got a line of each color.
Woo hoo! I got me some color now, boy! Could actually adjust for proper fleshtones.
Bugs is once again walking around on GREEN grass.
What I ain't got is a picture that fills the screen. The bottom fourth is still blank and I think the linearity is still off, no matter how I mess with the height/linearity controls (which, by the way, got cleaned with some contact cleaner spray. Didn't make any difference in what they do, but I'm not getting those sizzling noises any more, which is progress of a sort.)
Any ideas where to go from here? I'm tempted to either replace all the tubes on the chroma board (which seems a little drastic since they've hardly gotten any use) or just pulling the tubes again and cleaning the pins, maybe with a Dremel Tool or something. Does that sound like a plan? Or like a
stupid plan?
And now there's a PINK Dualette up on Ebay that I have my eyes on.
Of course, it doesn't work.
