Is there anyone who could perform an alignment on my FRG 7?

Just to clarify, this receiver uses a Wadley frequency converter front end. Alignment needs a wobbulator or sweeper and an oscilloscope to adjust shaped bandpass filters (2 of them)

Hi David yes that is correct. I have the instructions on how it should be done but none of the equipment to do it!
