Jim Fosgate Vintage Headphone 2002 Prototype Af-4 Tube Amplifier El84

  

This was one of Jim's personal hand built prototype units. Working and sounds great I might add. This is a chance to own a small piece of audio history. While testing I noticed the tubes were getting a bit hot. I don't have a schematic so you need to have a tech or be able to do work on these units.

Amp runs sovtec el84 Amplitrex tested. This is the only one like it. Built into an eico chassis!
