Douglas Self Preamp Linear Audio 5 kit, Boards Built and Tested

Everything in picture included. $200 pp fee-free shipped USA.

I built and tested this -- all controls work as they should. I did not test the XLR inputs and outputs (see below).

This PCB has the motor volume control. An extra 5k motor volume control is included, also an extra 5k "regular" pot. Also a remote controlled pot board that may or may not be adaptable to drive the 5k motor control.

The power supply board was populated with a similar spec transformer. Also included is an extra 300ma power supply. Extra ribbon connectors.

All IC's are populated. The XLR jacks were not soldered-in as it would probably be wise to wait until you have a chassis machined in case they need to be shifted ever so slightly to match the openings.

Also included is a case for the power supply board with connectors in "case" one wants an umbilical supply.

I found this preamp, while very nice, is more complex than my needs require, thus stopping any motivation I had to purchase a proper enclosure for it.
