feedback in the output stage – Astoria

8. POWER INDICATOR
This will light and glow amber when the
power switch is in the ON position.
9. STANDBY
This switch is used in conjunction with
the mains power ON/OFF switch to
'warm up' the amplifier before use and
to prolong the life of the output valves.
Always ensue the STANDBY switch is in
the STANDBY position before switching
the amplifier ON.
This allows the application of the voltage
required to heat the valves to their
correct operating temperature. After
approximately two minutes the valves
will have reached the correct operating
temperature and the STANDBY switch
can be engaged by switching it to the
ON position.
In order to prolong valve life, STANDBY
alone should be used to turn the
amplifier on and off during breaks in
performance.
10. ON/OFF
This is the mains power switch for the
amplifier. When switched ON, the power
indicator will light and glow amber.
