I'm trying to locate the three diodes in the horizontal circuit and easily found the one on the horizontal output. Here's the thing. The one on the output (CR218) looks just like a diode should (as far as my knowledge goes they're cylinders) and so does the boost (CR219). However, the other boost (CR221), which is the same part number as the other two, looks completely different. It's similar, but looks pregnant. Is this the same thing, and just an different manufacturer?
I'm attaching an image of what I found in the place the SM says is the CR221 (part # 103-193).

Yes, that sure is a diode. Now I'll throw my two cents in... it sure looks like you have a 'ring' in there somewhere... have you checked the yoke for any caps??? It would be a perfect L-C circuit to oscillate... just a thought. I'll make it four cents... take a trip to a hamfest and buy a decent triggered scope with a calibrated timebase and some high zoot probes... sure would make life easier!!
Best of Luck!! Jim

Figures, the Hamfest here is this month and I'm not able to go those days. So any idea why that diode looks completely different than the other two when they all have the same part number?
