Power amp standby switch: Use this switch to silence (0 position) the amp when you
take longer break. The amp's tubes stay nice and toasty, and the amp is ready to roll
immediatelywhenyourampitbackuptofullpower.
Ontheone hand, the amp'ssurveillance system monitorsif speaker cordsare plugged
into , , and (78,76,75,and73).Ifnoneoftheseportsis
in use, flipping the Standby switch will not activate the power amp. This ensures the
ampisnotoperatedwithoutaconnectedload.
Inaddition, an electronicsurveillance system monitors theactive power tubes(that is,
two or all four tubes depending on setting). The Status LED flashes to
alertyoutoadefectivepowertube,blinkingindifferentpatternstoidentify thegiven
tube. Specifically, it lights up briefly at regular intervals - once for V1, twice for V2,
thrice for V3, and four times for V4. Because the tube monitoring system only works
when the power tubes are up and running, this indicator is not enabled until you
activate the power amp by flipping the Standby switch. To reset the power tube

I suggest you get into the habit of using standby during short breaks. In this mode,
