Our Hoefer PS 500 electrophoresis power supply is drifting upward
significantly after a short period of time.
I have a schematic for the power supply.  I am looking for a users
manual and troubleshooting guide.
Can anyone help me.
(The Hoefer  technical support group could only supply the schematic.)

Thank you
