Connect BOTH the IEC mains power cords to PSU and main unit, then the umbilical
cable from the PSU, which should be installed on the floor, as far wawy as possible
from the rack mounted main unit. The umbilical cable sockets are 4-prong for the
heater supply, and 5-prong for the anode supply, and 12V supply.
1. OPERATION
Connect the unit before switching it on.
Make sure that all of the external connectors are plugged into the Variable Gm
sockets, then switch the unit on.
Power up the unit and allow it enough time to stabilize before using. It usually takes
30 minutes to 1 hour before everything has stabilized and for the unit to warm up and
sound at its best. And of course remember to leave 1-2 inches on top so that air can
flow up and away from it. Definitely avoid that the heat gets trapped with no place to
flow, this way you’ll literally bake up the internals, shortening lifespan of the caps
and tubes!
