No.029 - Alesis 3630 Compressor Repair

This Alesis 3630 Compressor sits below my Tv in the house between the satellite receiver and my audio amplifier, but

it developed a fault. In this video I analyse the problem, effect a repair and do some other work to the unit.

UPDATE: I eventually change dthe PSU for a used unit I found on Ebay. 10VAC output off-load.....perfect.
