7.1.1 PCB Standoffs
Install the two (2) additional PCB standoffs on the back side of the board.
7.1.2 Tube Sockets
The tube sockets get installed on the back side of the board, too.
The tube sockets are installed as shown. The noval sockets only go in one way
(on the back side). However, the octal sockets need to be properly oriented with
the circuit board. Position the notch in these sockets so that they are pointing
toward the two noval sockets.
Do not solder them into the board yet !

you are doing a scratch build, put in both novals. Lift the PCB up into the chassis
guiding the tube socket(s) into the newly drilled out holes into the chassis.
Align the standoffs with their respective chassis holes and fasten them with a
couple of screws.
Now that the tube sockets are sandwiched between the circuit board and the
chassis, flip the chassis over and rest its top side (face down) on your work
bench.
We want to fit the socket(s) to the chassis drill holes. In a sense, it (they) will be
custom, or perfectly, fit to how you drilled the chassis.
