Time to solder the sockets now. Notice that the sockets for the PT2399 are 16 pin type, and the
ones for CD40106 and TL074 are 14 pin type. Put the 4 sockets in place and turn the PCB trying to
maintain the sockets in place. Using a plastic or a wood sheet will help. Solder the 4 sockets.
We will follow with the diode and the film & ceramic caps. Start with the film capacitors. Like with
the resistors follow the BOM and solder by groups. Start with the 10nf C9, C10, C49, C50, C51, C52,
C53. Solder it and continue with the next ones.
