A lot of bad connections I guess?

Kind of an unusual CRT filament ckt..Stby is a normal; tranny...but RUN if off of the FLY. Something like the Moto "JA SMPS "ckt-- that Switching supply powers the tube in RUN...but a small tranny does it in stby..


I STILL wonder...how the "old school techs"...handled the JA power supply...back "in the day" Today--it looks a LOT like a typical chopper SMPS--which is VERY familiar..but when it was in CURRENT production? I would guess it gave a LOT of headaches !!
