And any suggestions for best place to get it.

R209 is 3 series connected sections, 5300, 500, and 500 ohms. The middle tap (default setting) is at 5300+500, or 5800 ohms. Possible settings are 5300 (bottom tap), 5800 (middle tap), or 6300 (top tap). This is the horizontal linearity adjustment.
Could be replaced with a 6.8K 50W adjustable wirewound, set for 5800 ohms. The original is only rated at 25 W, but a modern 50W unit is a closer mechanical fit to the original.
