1. MAINS INPUT
Connect the mains (power) lead to
the MAINS INPUT socket on the
amplifier before plugging into the mains
electricity supply.
Important Note: The MAINS INPUT
socket has an integrated fuse
compartment. As with the HT fuse,
always ensure that the value of any
replacement fuse matches the labelling
on the amplifier rear panel. Always
switch the amplifier off and disconnect
it from the mains electricity supply
before attempting to access the fuse
compartment. If in doubt consult your
Marshall dealer.
2. HT FUSE
The HT FUSE will blow to protect the
internal circuitry if necessary. This
can sometimes happen in the event of
output valve failure. Replace the fuse
only with the value shown on the rear
panel. If in doubt, contact your Marshall
Dealer.
Important Note: Before attempting to
change fuses you MUST ALWAYS first
switch the amplifier off and disconnect it
from the mains electricity supply.

Important Note: Before unplugging a

it from the mains electricity supply.
Switching on without a speaker load
WILL damage the amplifier. NEVER
attempt to connect more speakers than
rated.
