[R-1051] R-1051 IF alignment - advice?

[Nick England]

If you are tired of my 1051-newbie questions, just hit delete. At least
we're exercising the listserver.

I'm now working on an R-1051. One IF/AF module has considerably more gain
than 3 others that I have. The others vary but have noticeably lower gain.
OK maybe the IF needs aligning.
Q. So how do you adjust those coils? - my screw-slugs are either varnished
in place or have heat-shrink plastic holding them. I tried just turning
that shallow slot and crumbled a little ferrite without much success
turning. Uh-oh. figured I'd stop and ask the Big Boys for experienced
advice.

Or am I barking up the wrong tree here and the more likely problem is a
leaky cap or somethin'?

Thanks for your patience and advice,
