The varactor diode D1

Now solder in the electrolyte capacitator C15 (100 µF). Observe installation direc-

tion. The plus pole is marked on the PCB. The minus pole is marked with a white

dash. It points towards the IC. Then install the ceramics of the capacitator C17 with

100 nF (print: 104). The installation direction is not important.

The capacitators

Last, you need to install the transistors. Do not swap the two types. T1 is a PNP

transistor BC557B, T2 is an NPN transistor BC547B.
