HUNT AMPLIFICATION

No idea who built this amp - appears to have been more or less a JTM45 preamp mated to a fixed-bias EL84 output.  Hammond transformers, using possibly a Hoffman style layout.  Anyway, I converted it to a AC30 top-boost preamp replete with bright/normal channels, using a 12DW7 for the cathode follower.  I switched the output stage over to cathode bias, removed the negative feedback and presence, and added a Vox-style "cut" control.  Sounds pretty good, but still a bit of a mess inside.
