Biasing Continued - Unplug the V40 from the mains and remove the bottom chassis plate using a No.1
Posidrive screwdriver. Unscrew the 4 x M4 screws from the side of the top grill using a No. 2 Posidrive
and remove it. Carefully place the V40 on a clear and secure surface upside down so all its soft bits are
exposed.
The BIAS pre-set is found in the power supply section on the PCB, (yellow circle on photo). The Bias
voltage measurement is performed between the chassis and the test point TP8 & TP10, (yellow squares
on photo). Using a multimeter set on the 200mV range, measure these test points and adjust the BIAS
preset so the meter reads approx. 34mV. This translates into 34mA of current per output valve. Check
both Test Points a few times and try to balance the Bias voltage so it is as close as possible between the
2 valves. We don’t recommend a difference of greater than 6mV between the 2 valves.
Amplifier Dimensions:
SIZE (mm): 342(w) x 185(h) x 185(d) Unboxed. 545(w) x 310(h) x 300(d) Boxed.

Output Power
Please note that due to the nature of the waveforms involved when the amp is in Single-ended mode,
measuring the available output is very subjective.
The following measurements were taken at 240V mains input into an 8 Ohm load using a 1 KHz Sine
Wave with the output waveforms set just before clipping:
High Power: 42 Watts
Low Power: 7 Watts
High Power Single-Ended: 1.6 Watts
Low Power Single Ended: 0.5 Watts
