Where's this wire go?

Got a schematic? Know where the end below chassis goes to? Those details will tell all.

The service manual will tell that the wire is there to isolate an open tube heater, as this set is a transformer less series string set.
You were instructed to take a continuity test between that wire and the chassis for a part of the series string and from that wire to another point, probably the damper tube socket. It was supposed to make open heater troubleshooting easier.
I did it both ways, pulling tube from the beginning of the string and from the end. I never took me that long to find an open heater. I knew the tube heater pins by heart, so I could do it real fast with an Ohm meter.
If the tubes light, your problem isn't there.
Motorola did the same thing!

I've got a Sam's but the spot where the wire is located is so fuzzy on the diagram I can't tell. It's a short wire and only reaches a few spots. I'm wondering now if it was not meant to run throw that hole since it was sticking out straight. I tested it and it's has a slight current so I assume it has a point not just a random exposed wire that is hot placed there just to mess with a guy 60 years later
