With respect to vacuum tube levels, it's about as low impedance as it's gonna get so i sure hope it works. After all, it only needs to drive a potentiometer's resistance and it's own frequency adjustable feedback loop. I'll post when i'm done, it will be a while. I'm redoing the wiring to be tidier.
