Roger and Geo:
?tried a simple series regulator
R6 is a dummy load of 100M( manually swept it down to 10k and seems to work)
Q2 is a cheapo 2n3904 and so are Q1 and Q3?
choice of Q2 depends on how much voltage needs to be dropped.?
If only 30V needs to be removed, ok.?
If 200V needs to be removed, need to pick a higher voltage tr for Q2
