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
4 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.
SERIAL NO: Displays the model and serial number of the unit.

the amplifiers performance and in some cases may cause damage to your amplifier. Try the L20H into a Laney Lionheart LT-
212 cabinet - you will be amazed what this little baby cranks out.
