Thank you!

I made the power supply PCB's myself. These where created for another project a couple of years back. And since I still had a few bare PCB's available I used those. The power supply is built around the LM350 (or NTE1929 is also an option). These are 3A adjustable regulators. Both PCB's, which are stacked upon each other by means of 45 mm standoffs, are set to output 5 volts.
The toroid transformer has two secondary windings, one for each power supply board.

The small PCB behind the transformer in the image is a 12 volts trigger input. The player can be switched on and off by a remote device.
