Beckman Industrial 9020 Oscilloscope Repair and Discussion

Detailing a repair on my Beckman Industrial 9020 Oscilloscope. I had previously completely disassembled this 'scope , cleaned the controls and replaced some defective capacitors. Also, replaced all the BNC receptacles as the originals were quite corroded. Also discussed how I plan to use this 'scope while introducing a companion piece, which will be my next project.

I acquired one of these 3 weeks ago from 1978.
Having fixed noisy selector switches, potmeters, pushbuttons with prf 7-78, it turns out
to be a troublefree scope for 60 euros. Thanks for the steady video using a tripod.

I have a 9100 100mhz BI with no trace, are there any service manuals online? I have never been in a scope, but I have an electronics background.

Did you find a service manual?
