-the back of an amp
We have quoted the back of an amp to stress the importance of putting safety first when
working on this type of equipment. Tube amps operate at high voltages which have the
potential to kill. Only work on an amp when you are wide awake and sober.
Please make sure you do the following before opening your amp:
Turn the power switch off.
Turn the standby switch off (down position).
Unplug the power cord.
Give the power tubes 10 minutes to cool down.
When the amp is open:
Use a volt meter with alligator clips to measure for high voltage at several test points.
