Now take the short wire from BAG #2 - we will be using this
to hardwire from the 8-pin valve base to the 9-pin valve
base.
The graphic to the left shows the
connections for the twisted wires.
EXPLANATION: On the M2 Power
Supply Board we will have 2 different
tubes - a 6X5 and an ECL82. As
explained before, in order for tubes
to operate they need a filament
voltage - we will be supplying 6.3V
AC to both of these tubes. The wire
we are installing here is used to
"parallel" the 6.3V AC that will be
coming from the secondary of the
Mains transformer.
Note in these pictures the twisted wire
has been soldered into pins 4 & 5 on
the 9-pin valve base.
On the 9-pin valve base note the
upper and lower holes through the
pins. Connect the current red & black
wires to the lower hole on the valve
pin.
