BEFORE USING YOUR AMPLIFIER
Speakers
Always ensure the correct speaker load (Ω) is connected to the SPEAKER OUTPUT terminal(s) at all
times during operation. The speaker outputs are found on the rear of the amplifier. The minimum
total load is 8Ω. Only connect cabinets as described below.
1 x 16Ω cabinet – Use the 16Ω speaker jack socket (Rear of chassis)
2 x 16Ω cabinets – Use both of the 8Ω speaker jack sockets (Rear of chassis)
1 x 8Ω cabinet – Use either of the 8Ω speaker jack sockets (Rear of chassis)
Note:
Never use instrument cable to make speaker connections.
Use only quality, unshielded speaker cable.
Speaker cabinets must have power handling at least equal to the amplifier’s rated output
power.
Never use two cabinets of mismatched impedance (Ω).
Valves
To prolong the lifespan of the valves installed in the amplifier, when switching on the power to the
amplifier, set the 15WATT/STBY/7WATT selector switch to the middle position (STBY) for
approximately 2 minutes. This places the amp in STBY mode (Startup Tension Bypass, historically
known as ‘standby’ mode). This allows the valves to reach the correct temperature. After 2 minutes,
switch to the PLAY position.
