[Boatanchors] Morrow Modulation Question

Many thanks for everyone's help and advice regarding my Morrow problem 
of "light" AM modulation.  I believe that I've finally found the root 
cause -- a shorted winding in the modulation transformer!  [I haven't 
taken the transformer apart yet to verify, but this hypothesis best 
explains the most recent measurements I've made on the transformer 
performance itself.]

Oh well -- what to do now?

Anyone have any advice on rewinding a transformer?  (Anyone have another 
Morrow xmtr, working or not, they'd like to part with?)

And again -- thanks to all for your advice.  It was a huge help!
