I was afraid the magnetic tuning was hosed due to some coils being bad, tried the scope only to see no output whatsoever from the discriminator etc.
Then it occured to me to try to align the circuit, to which the procedure is there in the docs.
I aligned by ear, though obviously aligning by meter would be better; I also read sonewhere in Rider's they swapoed 85A and B trimmers, but decided to folow the instructions as mine are from Chuck and don't look like Rider's.

Anyway, tuning started to work, pulling in the signal when de-tuned, first from generator and then the local station. I might repeat the alignment, now with the meter.
If all works, I will assemble the radio and put to work.
