I thought I would detail my preamp project. I've had this idea for a while but only recently got around to starting it. Seen a couple of threads previously with similar intentions but looks like they never got finished…
I’m going to use an Arduino for control because I really like open source hardware and its so easy to work with. The Arduino will control a passive, relay-based input selector and Attenuator via I2C using a rotary encoder/buttons/remote. Not sure if I’ll use an LCD display in the final design but I have one at the moment anyway. Not sure about the tube stage yet but I’m thinking a Low Voltage Aikido (Aikido LV)
Attached is a diagram showing the general layout.
