OK. An update.

I have completed the alignment process as per the Service Manual. Here is the situation now (starting with the IF):

- AM Reception is good, generally, although I notice that I lose signals on low frequencies of the bands - Band C, in particular. (Using my FT-991A to detect the LO I can see that the output level drops to zero as frequency is decreased. In the case of Band C, I suspect capacitor C103, 4000pF. Will investigate further.

- After working on the BFO I can receive and resolve sideband signals, but the audio volume level is VERY low.

Has anyone else seen these problems?

Best regards,
