I had a look at the trimmer board A and I think the adjustable 'transformer' is
T1 and not the trap coil (??).
There is also a 270pF capacitor which I think is
C21 from the secondary side of the transformer.
As for the trap there is a large 1000pF capacitor on there which I think is
C07.
However I can not see L01 unless it;s the small component between the trimmer and
C07 I marked with
?
Or maybe I'm wrong altogether ..
What do you think?
