What started as an effort to restore an outdated (1972) automobile distributor tester, has developed into a desire to understand the electronics of the power supply module. I have photos and a crude sketch of the elements of the module. My goal is to develop a proper schematic drawing of the circuit(s) and understand the function of each of the elements. The main function of the power supply is to drive a rotating plate that contains a flash tube, and to trigger the flash tube for stop action effect. Conductivity through the rotating shaft is by graphite brushes and copper contacts. I would also like to learn which components (if any) may be replaceable with modern equivalents.
Is this a proper topic for this forum? If so, I can scan the sketch for posting and start the dialog.
