SOLD: Doug Self DIY Linear Audio Preamp

SOLD

For sale is my Doug Self preamplifier, as described in Linear Audio Vol. 5, using the boards as described on this site, from Carl Huff. I built this a couple of years ago.

The gain for the preamp is about 1, and could be changed to a gain of 3.3 with 4 resistor changes. I just did not need all that gain...

Doug Self Preamp from Linear Audio #5

It is housed in 1U tall full width case, and uses custom front and back plates from Front Panel Express.

RCA and XLR inputs for 5 channels in, with both XLR and rca outs.

Balance, bass and treble controls as noted.

It works as expected, and is a very quiet preamp.

11 x 7 x 2 chassis, weighs 7 pounds.

I will ship to the continental USA only.
