Sun Electronic Engine Tester 820

[Waggy]

I have a Sun Electronic Engine Tester 820 with a Sun scope Model 80 and two other Sun 8x scopes for parts. Does anyone know where I can get the scope fixed or electrical diagrams of the scope? I think the scope needs a new transformer.

Is Sun still in business? perhaps do an online search and aee what you get.
