So, I've been trying to test these 1801's, but I had a bad yoke. i found what I think is a 2001 yoke (part of the label is missing but it ends in CE just like the 1801 yoke), but when i hooked it up I first got flyback buzzing (new flyback) and a distorted pic. Then I got no pic, no flyback buzzing, but some of those little things on the neckboard would light up and buzz. Plus, the B_ would drop in half with this yoke plugged in. Apparently it will not work.
So, I have another yoke from a different monitor that gives me almost the same reading as the 1801 yoke. i put it on an get a perfect picture (although flipped horizontally for some reason even though the yoke connector hasn't been changed). YEAH! uh-oh. After about 10 minutes of running, suddenly the flyback starts buzzing and the picture shrinks and gets all distorted. If I leave it off for a while so it cools down, it will come back up as fine for a while then repeat. I noticed the B+ was up around 145 at this time. I need to turn the pot all the way down to see if it helps or not.
I'm going to install a cap kit, but I was wondering if there is a problem with these chassis that can cause this issue, or if the problem is still with the yoke load?
For the record, the original 1801 yoke and the other one I am using have these readings:
H - 5.5
V - 15.5
What I think is a 2001 yoke has these readings:
H - 2.3
V - 15.5
If anyone has a good monitor of either of these (1801 or 2001) and can compare the readings, let me know...
