This is for the main purple PCB as well as the chassis top plate with no other parts (i.e. no Nano, no tubes, no PCB parts, no chassis) for the project described in the July 2014 AudioXpress magazine…

The Budgie Preamplifier is a vacuum tube-based, four source linestage with remote volume control. The 24V power supply means you can experiment with tubes at voltages much lower than typical tube voltages. The Arduino Nano simply plugs into the main PCB - it couldn't be easier. With the chassis top plate, the chassis layout and build is a breeze.
Pictures show a stuffed board, a wired up Budgie and a functioning unit. You can build the whole project for around $250 plus shipping costs.
This is a brand new design for 2014 from Shannon Parks at Parks Audio that uses an Arduino Nano micro in a tube preamplifier. Easily build a full featured tube preamp using the remote control of your choice via learning mode. It will handle four line inputs (sorry, no phono RIAA preamp). The design uses low voltage - only 24V - and is a perfect project for the either a tube or Arduino hobbyist. The code is COPYFREE - mod, sell, share, etc. It's yours.
