Hi - you should be measuring around 11 ohms across the green and brown wires of the first IF secondary. The green wire will connect to the 6K7 IF grid cap and the brown to ground. The 6K7 RF grid cap will measure around 51K ohms to ground. The difference is that the RF amp has grid bias and the IF amp has cathode bias developed by the 400 ohm resistor in the cathode circuit.

What is the value of the IF grid resistor? The more common circuit is the one in the schematic.
