They connect at the top side of the wire-wound 6.5kOhm resistor in parallel with that capacitor at the rightmost of the schematic, where it meets the Field coil. This point then goes to the shadowmeter, and the IF 78's load goes to that same point, and the RF 78 as well as the 6A7 loads, go to the right side of the shadowmeter.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

Those are details better left to the ones who know. Maybe you disconnected the wrong end of the wire.RodB — 06:22 PM
