My SE/30 is currently in the process of an overhaul and return to stock condition - this includes returning its original analogue board to it, instead of having used the SE's analogue board as a stop-gap.

I've replaced the SMPSU unit and it's functioning just fine - however the horizontal sweep is not.

I know this because there is a thin one-or-two-pixel-wide line down the center of my screen.

R19 isn't burnt or charred or out-of-tolerance, it reads as 221.4R - definitely within the 5% tolerance the design allows for.

I replaced some of the capacitors with higher-quality and higher-voltage ones - i'm not sure if this somehow did something or if I missed something.

Hence, I need a schematic of the analogue board with refdes corresponding to the component references on the silkscreen so I can know what's going on, preferably one with the different portions (rails, inverter, horizontal sweep, vertical sweep, etc.) marked clearly... Can anybody help?

Alternatively, anyone have any ideas?

EDIT The part numbers on the silkscreen are: 820-0206-C and 630-0147-F.
