Re: Kt88's took out my friend's VT 130 SE

The input circuit for the VT130 is much simplier than typical Audio Research input circuits, based on the tube count. How they are actually executed I do not know since I have never seen a circuit diagram. But after 25+ years of making tube amps, the circuits amongst all these amps are amazingly similiar. Minor variations on a theme.

I have never seen an ARC tube amp circuit that did not use a cathode follower as the driver tube. I would be surprised if this is not the case with the VT130.
