John - I don't believe change needed.  I modified a couple of 30S1s with a
1:1 small iso xfmr.  Only change was increased output to easily do today's
legal limit.  I also
went to a 4CX1500 because of the grid spec advantage over a 4CX1000 - tho I
never abused a 4CX1000 with
excessive drive.  Brgds, Geo
