20 W Stereo Integrated Audio Amplifier
PWB so it rests on the standoffs. The top of the socket (the side the tube plugs into) should
face outward. Loosely tighten the mounting screws. See Figure 5.2
a
.
– In a similar manner, mount the tube socket on the rectifier PWB.
– Install connecting wires from the PWB pads to the tube socket pins. Solder in place.
Materials for these steps can be found in the “Tube Socket Hookup” package. Note that
only the active pins need be connected at the socket. The heater connections are made
separately for the amplifier tubes. The recommended procedure for installing the
connecting wires is as follows:
1) Feed a bare wire from the component side through the pad and into the socket
soldering tab.
2) Crimp in place (see Figure 5.2
b
).
3) From the component side, pull the wire tight and solder in place.
