But we all knew that, right?
Here's the deal; remember thatn NOS Dumont that Doug found at the beginning of the year? Well, I just bought it from captainmoody and it arrived yesterday. I was hoping it would be plug-n-play like the roundie I got from Doug, but no such luck. I'm hoping the problems will be easily solved.
First of all, I think it needs to be converged. The color in the center of the screen looks okay, but as you get to the top and the bottom, you can see individual red, green, and blue outlines. Is there any way I can converge this without A) some expensive piece of equipment and B) knowing what I'm doing? There's a service switch on the back that turns the picture into a single horizontal line. Is this of any use?
And speaking of switches on the back, this set has like a gazillion knobs and buttons and things, some of which aren't even labeled! What the heck is "kine bias"? The switch has three positions. Green drive? Blue drive? There's no red drive. Then we got the Red/Blue/Green Screen knobs. Haven't touched 'em, as I'm afraid I'll mess up something really bad. I think I can figure out "color killer", but there's another knob right above it that's unmarked. Not to mention the other unmarked knob that's next to it. Add some little knobby thing on the end of the picture tube, and it's no wonder I'm confused!
Second, the sound is really terrible. Sounds like interference and static and just general awfulness. Muddy might be the term.
The last big problem is the vertical linearity is way off.
What are the chances that any or all of these problems can be fixed easily, like with adjustments or replacing tubes or something? Anyone got the schematic for it? I'm thinking that might explain the Mystery Knobs. The best I can figure is that it's model STAMxxxx. Can't figure out the last four digits. It's chassis # 55T01. Doug: might you still have the paperwork that came with the set?
I throw myself on the mercy of those of you who know what you're doing! If you've read any of my previous posts, you'll know that (well, besides being whiny and lame-brained!) I'm pretty ham-handed when it comes to electronics. I like watching 'em, but poking around inside just makes me nervous. P.S. I've already busted the on/off switch, but I think I got it fixed again.
So you see what you're dealing with...
Anyway, thanks in advance for the help! Once I get the thing running halfway decent, I'll post a picture.
