Enclosure 
To avoid hum, it is recommended to mount the K8084 and the transformer into a Metal housing. 
Drill the holes for the connections and the potentiometers. 
Hint:You can drill the holes for the knobs or the potentiometers and mount the knob afterwards. 
1 hole in the print (next to RV3) is provided to connect the earthing to the housing through the metal spacers 
or bolts. 
Hint: 
Mount the transformer as far away as possible from the circuit to avoid humming. 
It is recommended to leave this circuit under voltage; disconnect the voltage only when not in use for a 
long time. Always switch off the power amplifier first before switching off the preamplifier.
