pins can easily be bent and the plastic locating key on the output valves can be
snapped off. We recommend a slow circular motion known a ‘dweezling’
while lifting the valves from their bases as this will free them with the least
amount of effort and stress. Ensure that as you remove them that they are
never more than a few degrees from vertical to avoid bending or breaking pins
etc.
Please always try to buy matched pairs of output valves as they will be easier
to Bias and give longer service. Ensure the toggle switch on the top of the
chassis is in the correct position for the selected output valves, (either 6L6s or
EL34s). The VX ships with 6L6 output valves fitted but is available with EL34s
as a special order, (no extra cost).
Biasing Continued - Unplug the VX 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 VX 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 TP10 & TP11, (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.
