The front glass has the etched VAC logo. Install this between the front pillars.
Take great care not to scratch this glass.
The front glass fits into a small channel in the front plate.

Tighten  the  white  nylon  setscrews  that  secure  the  rear  glass  and  side
glasses. Turn clockwise to tighten.

There are four setscrews for each glass plate.

Do not tighten the setscrews for the front glass yet.

Install the six aluminum blocks at the top of the rear glass and side glasses.
If there is a ‘dimple’ in the block, it should face the outside of the amplifier.

Tighten the metal setscrews that secure each block using  the allen key
supplied. Turn clockwise to tighten.

Replace the aluminum top frame.
Ensure that the front glass fits into the groove in the top frame.
Ensure that the top frame sits flush in the pillars.

Replace  the  four  screws  that  secure  the  top  frame.  Turn  clockwise  to
tighten.

(Note: photo does not show the tubes or glass, which should be installed
by this time.)
