Hello..my first TV

Another question. With all the interconnect wires coming out of the chassis, I failed to notice, until now, a somewhat random looking wire emerging through a non-factory looking hole on the rear of the chassis. No connector, in fact no exposed conductor. Tracing the wire to its source, I find it attached to the plate of the 6AL5 "clamper" tube. Now, the socket of this tube is enclosed in a screwed down metal shield so access for any reason would necessitate first removing the shield. I am wondering if this was added sometime in the set's life to enable plate voltages to be measured for service purposes..
Stupid question...Should I just leave it hanging out? Could leaving it there possibly introduce any instability due to the fact that it originates in a shielded part of the circuit?
Also, the 1/2 watt resistor that is also attached to pin 2 is reading high , about 2.3 meg should be 1.5 meg according to schematic was getting ready to change and just looked at the parts list to confirm the power rating. Parts list call for 3.9 meg. I suppose I should go with what's already there. I'm colour blind but wifey confirms its brown, green, green.

The 6AL5 is associated circuit-wise with a 6SN7 (V11). What circuit is this in? Sync?

[Donj]

The 6SN7 is the phase inverter/clipper sync separator circuit

To venture a guess, maybe it was a test point that someone wanted to monitor with a scope.

Coot,
Another demonstration of what you know that I don't .
Dug into a portion of the manual that is way beyond me at this point and found the attached... Since I don't even have a 'scope at this point, I guess I wouldn't be doing any harm by removing the mystery wire.
