Amplifier Protection:

Excessive output voltage; shorted loads;
excessive phase shift; rf interference;
overtemperature; excessive back EMF;
In-rush current limiter

Load Protection:

Start-up/shutdown transients; dc fault;
infrasonic signals; low ac line voltage;
nonlinear signal limiter

Output Topology:

True complementary symmetry with
ungrounded collectors (no mica insulators
means better heat transfer)
