CONNECTIONS AND CABLES cont,..
Take care no loose strands of wire are visible between the loudspeaker
terminals, short circuits may damage the amplifier.
After making all connections connect the amplifier to a mains supply, ensure
the volume control is turned down to minimum and switch on.
After a few
seconds the valve heaters will begin to glow. After approximately 15
seconds adjust the volume control to the desired sound level, the sound
quality should be crisp and clear. If there is audible distortion or unwanted
noise switch off and check all wiring and connections.
If problem persists consult your dealer or telephone 01702 469055 for advice.
In the event of the amplifier becoming faulty please contact your retailer of
return the unit for manufacturers repair. Do not attempt to dismantle, modify or
repair the amplifier, to do so may invalidate the manufacturers warranty.
NOTE: No user replacement parts are fitted, return to manufacturer for repair.
ENSURE THE VALVE AMPLIFIER IS NOT SWITCHED ON WITHOUT
THE LOUDSPEAKERS CONNECTED.
OPERATION
Valves, or Themionic Tubes, are rugged components but they have a finite
operating life of several thousand hours continuous use.
Observation of the
following points will help prevent premature failure and ensure many hours
of listening
pleasure.
1Valve amplifiers warm up rapidly, it is not necessary or desirable
to leave the amplifier permanently switched on to ensure the best
performance. It is recommended that the amplifier should be switched
off when not in use to conserve valve life.
2Do not switch the amplifier on when hot, i.e. immediately after prior use,
always allow the valves to cool completely before switching on again.
3Always use the amplifier within it’s performance envelope, persistent
overloading, indicated by “clipping”, a clearly harsh and audibly
distorted sound, will shorten tube life.
The valve set supplied with the amplifier is guaranteed for 6 months only.
