Hello all, first post and thank you for allowing to join. I'm hopping to find a schematic for a Lee Jackson SP1000, unable to locate and Lee Jackson does not have any. Any help will be apricated.

Thank you in advanced

I love it that the circuit board has no markings to identify component numbers

You mean no silkscreen?

Lots of old stuff did not have it.

Sometimes, but not always, parts labelling was shown on a layout print, in the Service Manual.
