This set is quite problematic for a couple of reasons:
1. The set has been worked on and I am not certain what is original and what is factory. I have found some replacement components that are incorrect values
2. I have both the Sams and the OEM Halicrafters schematics. The Sams reflects later wiring and component values, and the Hali is earlier which more closely resembles my chassis. However neither schematic totally reflects what my chassis is.
3. The set has a separate power supply with HV flyback and B+ supplies. There are 4 multi pin connector cables going back and forth and trying to follow what all the wires do is quite a challenge not to mention trying to relate all these wires and connector pins on the schematic.
With that in mind I spent about 10 hours comparing the main chassis against both schematics. I decided that I would use mostly Halicrafter schematic values. However even then, there are a few changes that match only the Sams and are obviously production changes that are not reflected on the Hali schematic. So it's a mishmash but mostly like the Hali schematic.
I did find a few resistors that were out of range and at least one 1meg that was open. But when I powered the set back up, I now only have a raster without any video information.
I have not been able to work on the set powered up due to the cabling issues between the 2 chassis. My next step will be to devise some method of working on the chassis live. At that point I will attempt to see if I have lost B+ somewhere that may have caused the video to disappear.
I will post again after working on the chassis live so I can take some measurements. I suspect working on it live will be more fruitful.
Thanks for all your help.
