Assembling the circuit board

The following sequence is suggested
• Power supply components

  Apply a 100 Ohm load and add resistors to the regulator to trim the voltage to 3.3 volt

• Audio amplifier components

  Test that it works.

• Sockets for Q5, Q8, Q9 and Q11

• Pins for all external connections

• Sockets for microprocessor and Si5351 module

• All passive components except for the output/Class E components.

• All the semiconductors.

• Output/Class E components.
