Re: Center tapped transformer

Tim,

You can also connect a full bridge rectifier across the end wires and
get the following:

1) +42V and -42V (ground the centertap).
2) +42V and +84V (ground the "-" end of the bridge; the center tap is
then +42V).

Option (2) is useful if you have a mix of high speed and low speed
axies; use the higher voltage for the high speed ones.
