Hi Mike,
Yes, it appears your numbering matches with the proper phasing of
the one-turn feedbacks. But RV1 is 100 ohms ("100R"), not 100 k
ohms. That pot is set so both Source sides are the same voltage.
All the 2SK715s that Andrew Ikin used were of the highest Idss
version, "W", from the Sanyo datasheet, in the 3 different
ALA1530LNs that my group opened up and traced out.

Steve,

Also, I notice that the 2SK715 had four ranks for IDSS and
the 2SK932 has two ranks for IDSS.? Any idea of which rank was
used by Wellbrook?
?
Thanks again.
