22. Reverb
Control of the spring reverb effect level.
23. Master Volume
Master volume control.
HINT: Besides controlling the volume,
it influences saturation of the clean
channel. Therefore, when turned down
to a lower level, a crunch sound can be
obtained on the clean channel.
24. Lamp indicator
When glowing, the amplifier in on.
HINT: There is a 12V bulb under the
cover, which can be unscrewed without
taking the chassis out. If the light needs
to be replaced, turn the amplifier off,
unscrew the metal nut, gently push the
bulb in and turn left at the same time
until the bulb comes free from the
holder.
25. Stand By / Power selector
In position “Standby” - in the middle -
the amplifier is ready to work. Changing
it to positions “15W” or “30W” sends
anode voltage to the tubes – in these
positions the amplifier plays.
In the “30W” mode, the amplifier works
with full output power – then all output
tubes work. In the “15W”, the amp
works with half output power. Then only
two output tubes work.
HINT: You should keep the switch in
the “Standby” position if there are long
breaks between playing. You should
also wait about 1 min. between
switching to the
Standby and turning
the amplifier off.
26. Power
This switch turns the mains of the
amplifier on or off. The amplifier is off
when the switch is in position “up” –
then the lamp - 24 is not illuminated.
The amplifier is on when the switch is in
position “ON” – the switch is illuminated
in red. In this position the amplifier
does not play, but tubes are hot, and
you can change channels.
HINT
:
Before turning the amplifier on,
always make sure that the Standby
switch is in position “up” – it will extend
the life span of the tubes. The amplifier
should be turned on in the following
way: first, turn on the
Power switch and
wait about 1 minute. Next, you can turn
the
Standby in one of directions.
The turning off procedure, works the
other way around. First, turn the amp
into the Standby , then wait about 1
minute, afterward you can turn the
Power off.
