Hello fella's,
Have a question on a zenith 9s367 chassis that I brought home yesterday.
Upon looking it over, I noticed a .05 cap that was hanging by one end.
It is attached to pin 2 of the 6J5 detector tube and a 3 terminal strip above and to the left of the tube.
I am not seeing this cap on the schematic.
I see a C4 .0001mfd cap on the schematic.
Is there a reason that this disconnected cap was installed there?
It is not a zenith cap, so it is not original.
Was there an upgrade?
Otherwise looks like very minimal work has been done to this chassis.
