unless I am wrong ! The adjustment just wont be quite as precise.
Looking at the schematic the wiper(center) goes to the "plug" wire (CTR).
One end goes to C of video out.
Other goes to JCN of R239 & R238.
If you dont take out R239 & R240 they are in parallel with
the pot cutting the ohms in half & reducing range.
1)Nip off R240 at the C of Q206
2) hook up only the wire to CRT to center of pot.
If you nip the R deep in the TS you can tack it back on
& nobody will ever know if you change it back.

Since the circuit is a voltage divider, can't I just connect T1 to the Hi tap, T3 directly to ground and T2 to the CRT lead? Wouldn't that give me a separate voltage divider while being able to leave the current one untouched/unused?
