Pre-main amplifier, the first product of Clique.

A large toroidal transformer is used for the power supply section.
A semiconductor switch is also used to cope with noise when the power is turned on.

Glass epoxy boards, which are not normally used in this class, are introduced and CAD design is introduced to keep the signal path shortest.
