I don't know anything about this set. Is it a superhet or TRF?

Is 375 metres (800 Kc/s) above or below the present tuning range? If the lowest frequency tunable is above 800 Kc/s you'll need to add a capacitor in parallel with the tuned circuit(s). On the other hand if the highest frequency tunable is below 800 Kc/s you'll need to remove some capacitance or inductance.
