I tested the power supply yesterday and today connected it to the rest of the synthesizer. And wouldn’t you believe – things appear to be showing some signs of life! A couple of LEDs are not blinking – I would find it hilarious if I wired them up the wrong way – but VCO 1, the white noise generator, the, ADEG 1 and ADEG 2, and the LFO, are all putting out the correct waveforms. VCO 2 is doing something completely weird that is going to be “fun” to debug.

All the wiring for under the board is done, allowing it to be mounted and the wires as seen in the photo to be soldered to the board.

The main board is coming along, this is before I placed the remaining capacitors and IC sockets.
Here I’m matching transistors with an ATmega328-based component tester.
And then the placing the potentiometers, sockets, and switches on the front panel

The supply that powers the +/- 12v rails is done! I think I’m about 1% of the way there.
