I finally reached the point of being able to plug in my Motorola TS-4C or earlier
, today. I still have more to do, there is hum in the picture. the focus doesn,t seem to work. This set was repaired/ modified before, parts were added most likely because someone was working from the wrong schematic.
Other than recapping, I had to repair the HV oscillator secondary winding, make up a ballast substitute, repair the broken HV pot extension I was looking for, and make a HV oscillator cover.
After adjusting the tuning slugs to channel 4 I got an image from a VCR on the screen, I was suprised to see how stable the horizontal and vertical were. I had more trouble with my Garod 1244G's horizontal sync when I connected it to the same VCR.
This TS-4C has channel 1, horizontal and vertical blocking oscillators, and no AFC.
