Our next task is to install the heat sink against the chassis which will be used by
the Filament Section of the Monoblock. Basically the 300B tubes receive a 5V
DC filament voltage via a regulator that needs to be heat sunk in order for it to
operate properly.
We will be installing two bars against the chassis.
Here the first bar is placed against the chassis.
Note this is the bar with just two holes in it .
The second bar that is placed on top.
Use the M4 countersunk screws
provided and thread them through the
front of the chassis.
Place the second heat sink with the 4
holes on top with the countersunk heat
sink holes facing up!
Tighten with the M4 nuts.
Now take the M3 25mm screw and the
M3 spacer and install such that the
spacer secures the screw into position
(see next illustrations also).
