USING THE AMPLIFIERS
Once all the connections are completed and checked, turn on the amplifiers by
using the rocker switch located on the rear top right of the back panel just above
mains inlet socket. The amplifier requires approximately two minutes initializing
time before it is ready for operation. During this time ensure that the volume
control on your preamplifier is at the minimum setting.
A new amplifier requires about 200 hours of initial use (called "bedding in time")
before the circuitry becomes stable and optimum performance is realized. As the
amplifier "beds in" the sound will become increasingly smoother, detailed and
open. Once the amplifier has "bed in" a warm up time of approximately 30 to 45
minutes is required each time the amplifiers are switched on before optimum
sonic performance is reached.
CAUTION – Valves can reach very high operating temperatures when in
use and can cause burns if touched.
