We've had a discussion before about the Franklin. The image from the component side is from a silver 11Z Franklin. You have a later 10A black one. Regardless, the alignment procedure is more or less the same for all Ranger radios from that era. Is the radio off frequency on all modes ? The 3 vertical coils control the oscillator frequency on AM/USB and LSB. It might be the crystal itself that's off , but you should be able to tune it back using those coils if it's only 1/2khz off
