Based on a high gain
Marshall circuit this article is reprinted (with
updates and improvements) from Vintage Guitar Magazine - Dan Torres's
"Amp Tips" Column.
This project contains a
WHOLE LOT of advanced tube amp technology and
just about everyone will learn some good stuff from it.
It features a tube
voltage regulator in the power supply for amazing
low noise, biased filaments and why - a couple of versions of the power
amp driver circuitry including incredible sounding EF86 drive circuits
(in stereo no less!)
All the schematics are
included here and real good detail on design and
building the unit. as a project box or in a rack mount cabinet.
The power supply alone
is worth looking at. I have used this same power
supply since this time in just about every preamp design and project.
A great, fun project
with tons to learn from.

oh yeah, the picture is NOT the preamp. It is the phase inverter for the Supro Thunderbolt.
