These film caps can also go into the board without an orientation. Some people feel that paying
special attention to a film capacitor's 'outside foil' can make a difference – feel free to learn

7.3 Final Assembly of the ECF80/EL34 PCB
Now you can install the valve bases. For the 8 pin sockets be sure to match the notch on the
valve base with the PCB. Take your time soldering on the underside of the board as they
will require a fair bit of heat and solder to adhere them to the board! Take your time! No
rushing!
Install the standoffs for the board: you will note there are 9 standoffs: use the M4 screws to
secure. Let's keep the ECF80/EL34 PCB out of the chassis for now as we are going to work on
the speaker posts and RCA section and its easier with no board in position.
