[Heathkit] SB-610 sweep help needed

[Michael Tortorella]

Greetings, all: I just finished refurbing an SB-610 (new caps, resistors,
rectifiers, etc.) and I can't seem to get the sweep circuit working.  Does
the 610 have well-known failure modes in this area?  Would appreciate the
list wisdom before I start shotgunning as I am not an experienced
troubleshooter.  Also, does anyone have an extra graticle (the green screen
with the grid marks on it) for this unit?

Thanks for reading and 73 to all
