I got a non-inverting preamp built to the posted schematic.
Sort of like TK's preamp but with parts I had on hand.
The Zout @ 1k is about 7.5k ohms and there is a bit of a rising Z slope from 100HZ down.
I have short rca cable runs, so it does not seem to matter.
A larger uF output cap would lower the Zout and flatten the Z curve at lower Hz's.
You could remove the 4.7k isolation resistors if a subout is not needed.
