connected to a speaker cabinet of the designated load rating using an un-shielded
two conductor cable for speaker use at all times during operation. Never use a
guitar cable to connect the amplifier to a speaker as this presents the amplifier with
a ‘capacitive load’. This can cause instability or oscillation which may seriously
damage valves and/or the expensive output transformer.
Always ensure a speaker is connected to the amplifier before powering up or
damage to the output transformer may result. Never unplug a speaker when the
amplifier is ON as this is even more likely to damage the transformer and the
output valves.
The output transformer in the VC35D has 3 separate secondary windings; a 16 Ohm, an 8
Ohm and a 4 Ohm. This makes it easy to connect many different combinations of
speakers. There are five speaker output jacks: 1 x 16 ohms, 2 x 8 ohms, (wired in parallel),
2 x 4 ohms, (wired in parallel).
Here are all the possible combinations:
1.
For a single 4 Ohm cabinet, use either of the 4 Ohm sockets.
2.
For a single 8 Ohm cabinet, use either of the 8 Ohm sockets.
3.
For a single 16 Ohm cabinet, use the 16 Ohm socket.
4.
For a pair of 8 Ohm cabinets, use both of the 4 Ohm sockets
5.
For a pair of 16 Ohm cabinets, use both of the 8 Ohm sockets.
Always ensure a speaker is connected to the amplifier before powering up or damage to
the output transformer may result. Never unplug a speaker when the amplifier is ON as
this is even more likely to damage the transformer and the output valves.
The VC35D Combo is fitted with the flagship Celestion Alnico Gold speaker @ 16
Ohms. This will be plugged into the 16 Ohm output on the rear of the amplifier. If
you wish to add an extension cabinet, this also needs to be 16 Ohm. When using a
16 Ohm extension cab, the internal speaker jack needs to be moved to one of the 8
Ohm outputs on the amp and the extension cab plugged into the other 8 Ohm
output socket on the amp, (see option 5 above). Details of the speaker can be

FOOTSWITCHES
TREMOLO (TIP) & REVERB (RING). This socket is for use with the supplied dual
latching footswitch to switch these 2 functions remotely.
FX LOOP. This socket is for use with the supplied single latching footswitch and
selects the FX LOOP (TIP of jack plug).
