Mains On/Off
– This turns the main power to the amplifier ON and OFF.
BACK PANEL FEATURES
AC Power Inlet
– This is the main AC connection point. It is an IEC type
inlet and also serves as the fuse carrier. Replace the fuse only with the same
type and size as the original.
FX Loop
– This loop is located post the tone controls and is just prior to the
amplifier input.
Tuner Output
– This provides a full-time output for connection to a tuner.
Direct Recording Output
– The direct recording output is fully balanced
and has the ground lifted as the standard configuration. It is configured for
both Pre and Post tone with the provided switch. The output level can be
adjusted with the level control positioned next to the pre/post switch.
Speaker Impedance Selector
– This switch should be selected to match the
impedance of the enclosure. Note:
This should be done with the Amplifier
turned OFF.
Speaker Output Connectors
– Connect the loudspeaker here. Connect the
speaker before turning on the amplifier. Do not disconnect the speaker while
the power is on.
IMPORTANT NOTE: Do NOT use your VT-300B without a speaker
load. Doing so will cause damage. Running this amp without a speaker
load is a VERY BAD THING. Don’t do it. Ever. Remember, this is a
vacuum tube amplifier, not a solid state amplifier.
Cooling System
– This unit uses a continuous flow cooling system that is
always in operation when the power is on to the amplifier.
IMPORTANT NOTE: Excessive heat is a Very Bad Thing and can
result in severe damage to your amplifier. DO NOT bypass or
disconnect any part of your thermal safety system. Doing so will
immediately void your warranty!
