GENERAL

THEORY

The

F-50-1

Inverter

Follower

Input

Stage

consists

of

two

stages

which

amplify

a

low

input

signal

to

a

usable

Line

Signal,

components

Rl,

clip

the

input

at

16

volts

peak

This

clipper

circuit

provides

input

regulation

and

surge

for

the

unit.

Transformer

Tl

couples

the

input

to

the

stage

which

consists

of

transistors

01

and

02.

Capacitors

Cl

and

C2

broadly

tunes

transformer

Tl

to

the

operating

frequency

of

the

unit.

Transformer

T2

couples

the

output

of

the

first

stage

to

transistors

03

and

04

which

makeup

the

output

stage.

Both

amplifiers

operate

as

switching

amplifiers.

The

output

coupled

through

transformer

T3

which

provides

outputs

for

driving

one
