Case No. 11) Sonic Frontier Power 3

A customer brought in a Sonic Frontier Power 3 power amp with a broken rotary switch.  The amplifier also has excessive static noise.

The problem was caused by a faulty rotary switch, and a ground wire which had fallen off due to a weak solder point.     However, the repair was very time consuming as the switch was inaccessible and the entire back panel had to be disassembled.   A rather unusual industrial engineering design.
