Purple Audio MC76 FET Limiting Amplifier

Serviced prior to sale. Sounding great! Oddly the meter wanders as you adjust the release pot in GR mode (with no signal attached). Purple have confirmed this is how they are all. We can provide extra info if needs be. 

Condition: Good - some marks from previous owners labels (see photos)
Accessories: Power cable
Voltage: 115-230V
