POWER INLET SOCKET: Connect to your power source. Make sure the specified voltage is correct for your country!
POWER FUSE: This is the main safety fuse for the unit. The fuse protects the AC power to the amplifier. USE ONLY THE
CORRECT SIZE AND RATING OF FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or fails and a replacement of the same size
and rating is installed and it in turn blows, the amplifier has suffered a malfunction internally and needs immediate service from a
qualified technician. DO NOT TRY USING A FUSE OF HIGHER RATING. Using a fuse that is too large in current rating may cause
serious, irreparable damage to the amplifier and presents a serious fire hazard. The mains fuse ratings are detailed in the specs section
at the rear of this manual
HT FUSE: This fuse protects the DC power to the tubes within the amplifier. USE ONLY THE CORRECT SIZE AND RATING
FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or fails and a replacement of the same size and rating is installed and it in turn
blows, the amplifier has suffered a malfunction, at this point check the output tubes and replace faulty ones if required. Should tubes
not be the problem the amplifier should be checked out by a qualified technician. Do not try using a fuse of greater value. Using a
fuse that is too large in current rating may cause serious, irreparable damage to the amplifier. Fuses are designed to protect, do not
take chances.
LOUDSPEAKERS: Loudspeaker outlets are provided on a series of five jack sockets. The impedance of the
loudspeaker/s should be checked and connected to the appropriate socket/s. Using the incorrect sockets will reduce the life of your
output tubes and won’t sound as good and in extreme cases could damage your amplifier.
IMPORTANT: Operation of your GH50L amplifier without a loudspeaker connected could result in expensive failure of your
output transformer. DO NOT OPERATE WITHOUT A LOUDSPEAKER CONNECTED.
There are dedicated optimised outputs for the following loudspeaker combinations:
1*16 ohm, 1*8 ohm, 2*16 ohm, 1*4 ohm, 2*8 ohm.
