I have reverse engineered the Magnetek 7345 converter used in many Chinooks
and attached the schematic here.

Red Land Baron, do you have an updated version of the schematic? The R67-R71 is connected to C24, for example, but it is not reflected in the schematic.

chin_k... No, I do not have an updated schematic. Due to the configuration of the component
mountings and the high current pc board traces, I was not able to accurately confirm where
the connections of the high wattage resistors R67-R71 terminated. I did not want to remove
components to see where the R67-R71 connection went to.

I think the resistors are connected to C24, but my PCB is not in very good shape in the area for me to poke around too much. See the Magnetek 7345 hot spots thread if you wonder why I bring the issue up.
