Well, its fixed..at least the hum problem anyway.

And Charles gets the...prize.  His advice was to check the improbable.  And
sure enough, the header was miswired.  The caps were never in the circuit.
Am I embarrassed?  That's an understatement.  Its amazing what filtering
can do to a power supply.  :)

Thank you all for the kind advice.  I learned/am learning a lot.

On to the alignment.  See my next note.

         Thank you again,

         Dennis
