It's been ages since I worked on one of those. I don't have a schematic in front of me, so I cant comment much. Does that chassis use the dual phasing diode? It's a tiny black plastic three lead component.
If it has one of those, it's a strong possibility, that's your problem.
In your reply, include the chassis number.
