[Amps] ORC Transformer

[LKBrownMD@cs.com]

Many thanks to W7HPW, K5GW, K6KWQ, K5PC, AF5B, and WB4BRA- your advice was 
right on, and I have the transformer working.  230 VAC between the 60 Hz and 230 
V primary taps yields 1160 VAC out from the 60 Hz and 1160 V secondary taps.  
Incidently, using the 50 Hz secondary tap instead yields about 1350 VAC.

The Amps group is great!

73 and best wishes for a happy and healthy New Year,

Lee, KI7UR
