How to replace the Mains Fuse
"All valve/tube amplifiers have potentially lethal voltages within.
If you are at all unsure of electronic repair, please take your amp to a
qualified amplifier repair technician."
Firstly locate the Mains fuse holder (on the back of the amp underneath the mains input)
Then using a screwdriver "pop" the fuse draw out, revealing the mains fuse:
If the fuse is “blown” then replace with the same specification fuse.
For countries that use:
• 220/240 volts, use a T2A fuse
• 115/100 volts, use a T4A fuse
If the fuse keeps on failing, then take your amp to your nearest orange dealer
who will be able to help.
