Custom Preamp / Small Amp Enclosure

Unable to source a preamp chassis that I liked, I decided to design and fabricate my own.

Attached are photos of a preamp build using a Broskie Aikido™ line stage, Erhard Audio phono and power supply boards, and an inexpensive relay-switched input PCB.

The PCBs are mounted on a sub-plate that can be raised with stand-offs, which allows for through hole and point-to-point builds.
