K2: Number of turns on T3: text and photo disagree

[David Woolley (E.L)]

I've wound T3 with 5 turns, but I found I had a lot of wire left over
and examination of the photographs in the manual suggest that the T3 in
the specimen assembly has 10 or 11 turns.  Is 5 turns correct?

David,

5 turns is correct.  The manual text supersedes any of the diagrams.
Yes, it used to be 10 turns, but that was long ago.

Tom,

T3 is the collector choke in the K2 PA.  I am not certain why the
inductance was reduced, because it seems to work with either.

There is no need to change it from 10 turns to 5 - but you can reduce
the number of turns if you wish, OTOH why 'fix' something that is not
broken?
