For your info the power supply in my FT-one I believe is the same as
used in the FT107.  I have a circuit diagram of it and it is called FP107.
It is not a switched mode supply, and I have repaired the first problem
in which the Bridge Rectifier had blown, but then the regulator wasn't
working. Unfortunately that is where the main problem is, in that it would
seem that this PC Board(PB-2117) had been worked on before and the 
copper was literally
falling off. I have no experience in designing PC Boards but am trying 
to make up something
to do the job, but it has to be exact size to mount in the power supply 
(mounting holes and
component height are a couple of the restrictions.
So while I work on that I was hoping to be able to connect an external 
supply to get the
rig going again in the mean time.
