Another linear PSU for Squeezebox

Here's one more 5V power supply for Squeezebox Touch.
Very simple circuit based on LM350 regulator (3A). Built on AudioSector generic PSU board.
50VA 2x12V transformer, MUR420 rectifier diodes. NOS Wicon 1000uf at the output. Bypass caps are MKT1822.

Enclosure is Galaxy GX148, which also works as heatsink for the regulator.
