Hi Gary:

If it helps, I have a UTC  Transformer  Cat# PF-1   It is the HV trans for a scope.  117 V. in  and 2.5 at the end of a HV winding, about 1KV.   The 2X2 goes on the one end and you ground the other to get Negative HV.   Interested???

My heart is broke. A year ago I agreed to go to NZ with wife.  Guess when?  Feb and March of this new year.  So I guess the AWA is going to miss the RCA this year.

Heard you on the BK, but couldnt get through.

Tim
