Smile My new BA-3, set up as a preamp gain stage

Click the image to open in full size.
Gain stage and power supply. There's absolutely no hum or noise.

Styling is derivative of my F4: actually this is just a really quick way to build enclosures (and pretty cheap). Aluminium angle from Ace Hardware, plywood and redwood cheeks from Home Despot.

The LEDs are a bit bright, but at least that's easy to fix. They stay on for a minute or so after I unplug.

Sneaking up on the gain stage. It connects to a passive front end that does switching and gain control: I may integrate them one day...

Click the image to open in full size.
Power supply uses a transformer rated at 50VA. Capacitors are 35V which is sailing a bit close to the wind (voltage under load is about 32V).

...Partially built, at Burning Amp.

Loving the music!
