Assuming a F96 & F97 are at least similar, field coil is in the power supply filtering ripple.
What's shown on schematic of 42 output is output transformer, humbuck winding & voice coil. You should measure resistances to determine just what purpose the loose wires serve, I'd suspect are to humbuck winding. It's resistance is listed as .2 ohm, while field coil is 880 ohms. Output transformer primary is 500 ohm and secondary .8 ohm.
Note the hum buck winding isn't absolutely required, will operate bypassed though probably with increased hum level. Polarity of that winding determines if hum is reduced or actually increased.
