"All valve/tube amplifiers have potentially lethal voltages within.
If you are at all unsure of electronic repair, please take your amp to a

(Always use a quality speaker cable, Never use a guitar cable
as damage to your amplifier may result.)

before they are “hit” with the amplifiers full power.

Doing this will significantly increase the live of the tubes.

You can then disengage the standby switch:
