is more easily, quickly, and safely done than with a conventional amp.

Caution: Replacing tubes is a job for qualified professionals! TSC merely
spares the technician the biasing effort.
What do the LEDs indicate?
Each LED is assigned to the power tube occupying that same position.
Getting a read-out of tubes' operating status and bias points is easy using

3.1 Automatic status indications
All LEDs light up and stay on.
All LEDs remain on for as long as the amp is in standby mode. They
will extinguish when you flip the Standby switch to Play after about 30
seconds. If the LEDs remain illuminated, the most likely cause is a blown
and
anode fuse that needs to be replaced by a technician. The anode fuse can
trip if a tube is already defective when the amp is switched on, and TSC
does not have enough time to measure idle current and shut the faulty
tube down.
None of the LEDs lights up.
The power tubes are operating normally.
One LED lights up continuously.
The tube assigned to this LED is producing no current. If the LED does not
extinguish after a few minutes, this tube must be replaced.
One LED flashes constantly.
The tube assigned to this flashing LED is generating overcurrent. It has
been shut down and must be replaced by a technician. If the second LED
lights up continuously, this indicates it has also been shut down for safety
reasons, but there is no need to replace it.
