This project is an all
tube, stereo, power amp, rack unit. I built it so that I can
feed a Stereo tube pre amp signal into a stereo T.C Electronics
G-major multi effects unit and then into a Stereo power
amp. The G-major effects
unit has stereo inputs and outputs. The stereo outputs let
you do ping pong delays and other true stereo effects such
as chorus. I happened to have a few pieces of a rack unit laying
around and so I pieced together what I had and used some
poplar to make the wooden parts. I raised up the floor of
the 3 space rack unit 1.25 inches to make space for the
point to point wiring.
This design is two 18
Watt Marshall power amps in one chassis. They share a
common power transformer that is made for 4 x EL84's in
class A operation. There are two 18 Watt output
transformers and one Fender 125C1A choke. The knobs on the
front are input level for each channel. The back panel has
two input jacks, two impedance selector switches and two
speaker jacks. |
