I had intermittent (1-2 out of approx 50 power ons) vertical on a newly
L201 in vertical section had opened up - 680uh...
I replaced with the closest I could find : a 1000uh....works fine.
I think a previous owner had noticed same problem because the vertical yoke
connector pins had been bent/twisted and tighted several times and one of
them just came apart when I did the same thing...check the vertical yoke
connector...Problem was most probably intermittent and he taught it was the
connector and tightened connections when vertical would go out.
I must admit these things arent really a pleasure to take apart...
Thanks those who offered help

Subject: Heathkit H89 - no vertical
I got a H89 with was seems like intermittent vertical problem.
The usual jiggling, tapping and connector checking does not seem to get
vertical going or not.
It was there at a few power ons.
Yoke ok, 330uf on board just before yoke connector was replaced because
Id like the schematics (scanned/emailed would be fine) for the board in
bottom of the H89 (video circuit).
