Alignment Question - 46-1213

[wakani]

Sailing along, down to the final stages, after re-capping I set out to align the set. Have a B&K SigGen, Frequency Counter, O'scope and VTVM.

First problem, the AM alignment, was with the 2nd IF transformer, TC402A. I can get no change in output from the transformer, regardless of how much I twist it. Trimmer C402A works fine, sensitive but not overly sensitive. Next on in squence was TC 400A, slight change in output but not near what I thought it should be.

Shortwave works fine.

AM is feeble

FM work fine.

Any ideas? Bad/gassy 7B7 IF amp?
