Sorry, Sir. That pic was taken pre-grime removal. All spiffed up now.
The cap kit may solve your issues, especially if the caps are of a quality brand like Nichicon and yours are in cruddy shape. However, the consensus is that the yokes are notorious for burning up, and after 41 years, the flyback may be hanging on by a thread, with today's replacements being a 50/50 shot at $55 a pop. There are around 30 caps on the chassis so I'm sure the old girl will feel (and hopefully look) better with a fresh batch. Surprisingly, mine only had two really bad ones: a tiny little 10uf 16v and the red one right in the center of the board whose value I don't remember. I figured I'd have a handful of crap caps but that wasn't the case.
