Mine looks like the firsat one you posted, only the door's gray, not white.
Hey, I adjusted a coil right near the 6GH8, between the tube and the chassis edge. I think that's the frequency coil, but it had an effect on the tint *shrug*. I spun *it* for good flesh tones and did well.
Trouble is, the core broke
And, the coil just 'north' of the 6GH8, I twiddled first, thinking it was the burst amp plate. It didn't do anything to the picture at all. Hope it's something easy - 3.58 osc output?
I adjusted the HV by turning the brightness to nothing and setting for 21.5kv. Well, I gotta retouch the convergence so I'll recheck it.
The infamous 6GH8 was bad. You'd have to jiggle the tube to 'bump start' the 3.58mhz osc.
What's those coils around that tube do? I'm guessing one's the rough frequency, the other might be the output? Oh yeah, and can you zoom back slightly on the burst coil, I'm having a bit of trouble locating it (which way is the front and back) and I don't want to diddle the wrong coil again! I'm trying to ID all the coils in the burst / 3.58 mhz oscilator circuit, since that's where my big troubles are right now.
What point can I ground in there to let the oscillator run free? I grounded W, but that killed the color.
