The power supply to my amplifier has an auxiliary adjustable stabilised 12 volt output which I want to use to run this preamplifier. I haven’t got room to fit another mains transformer for the K8O84.
Could someone please let me know what the + -voltages output are from the preamplifier’s own power supply is. I see there is a couple of 9 volt zener diodes in the circuit so perhaps it around 9 volts. Thanks for your help.
Please note that you need a symmetric DC power suppy.
Most likely it is a single supply.

I should have made myself clearer, my amplifiers Power Supply is +12v 0 12- and is adjustable. Please just let me know what the + 0 -voltages are on the preamplifier, I can then adjust my Power Supply accordingly.
-/+ 12V is fine.
