IA 36 volts  ok      IB 22 volts fails?
a6/b6 22 volts both ok
a5/b5 1.66 volts ok

IA and IB are wired together, perhaps you were measuring OB?

Deric,

Just wondering why you keep calling this a PCJJ?  It is a PJCCS -- meaning Paul Joppa Constant (or Compensating) Current Source.  It is not a Paul Constant (or Compensating) Joppa Joppa.

I am lazy , tend to leave out letts and make words short as possbible.
Yes I could have measured wrong point , after all it is balanced and sound is per spec before and after upgrade.
