Hi Bill and Gerald,
thank you both very much for profound suggestions to help with my
slugs ! Level 1 : heat; Level 2: hand-drill softly and replace
(both suggestions ended up in my 'reconstruction log book 'for
further references).
So far, Level 1 has helped to release a reluctant slug.
On checking further, I found a wobbly (?) 1730 (T1B in the
HB*-13C). After removing the can, I found a broken coil form -
electrically ok, but physically spoiled. I will try to stabilize
and then tune this filter precisely to the 1600 kHz IF (having a
1700 kHz quartz), so that I dont have to touch it any more. By the
way: the second filter (T1A) 1730 is of different construction
inside, so I got two versions.
I will keep you informed !
