[pyager1]

Hello and thank you in advance for any help that you offer.
I need a variable dual supply + and - output with only one variable resistor that will control both the + and - outputs I am using a 80volt ct transformer with another output of 25volts no ct.
Thank you

Have a look at this thread:

It may need a bit of a tweak for your exact requirements, but it is a one control bipolar PSU.

hi,
If you can get a 4194 power ic, you can easily make a dual voltage tracking psu.

Have a look at this pdf.
