TECHNICAL DISCRIPTION 

Power Supply:

 Self oscillating for reliability and efficiency. The transformer is 

epoxy dipped for extreme vibration resistance. Banks of high-speed 

TO-3

 

switching transistors provide massive current reserves. 

Output Stages:

 Transformerless, direct coupled and fully complimentary. Output 

transistors are high current and low distortion 

TO-3

 devices, operating at a 

fraction of their limitations. 

Protection:

 Our stable amplifier design is made virtually indestructible by three 

protection circuits. One is a precision thermal protection circuit, which prevents 
damage from high frequency oscillation, or an excessive ambient temperature. 
The second protection circuit is a current sensing device guarding against 
instantaneous abnormalities, such as short circuits. Both of these circuits 
automatically reset. The third form of protection guards against component 
damage from reversed power connections. 

Construction Features:

 Our unique, variable input sensitivity control permits 

optimal signal matching for lowest noise and lowest distortion with virtually any 
source. All components used are rated for at least 150% of their intended use, 
and are mounted on double-sided fiberglass epoxy circuit boards. 

Quality Control:

 In-house construction of critical components like transformer 

and chassis, as well as total assembly, allows 

LINEAR POWER™

 to maintain 

uniform quality. 

100%

 of the finished units are tested, then burned in for four 

hours, and tested again. Amplifiers, which pass this rigorous test, have truly 
earned the 

LINEAR POWER™

 logo. 

INSTRUCTIONS 

Read the following instructions through completely. If they appear to complex, we 
recommend you have an authorized 

LINEAR POWER™

 dealer do the work. 

MOUNTING 

1. The amplifier works best if it is kept as cool as possible. Mount in a position 
that allows air to flow freely through the fins. Be sure there is ample space above 
the amplifier to avoid trapping heated air rising from the amplifier. The amplifier 
should not be mounted upside down. Avoid mounting any amplifier in the dash or 
on the firewall to avoid noises being radiated directly onto the case. 

2. Mount the amplifier in a position that allows ample room for gain adjustments, 
and the installation, removal and attachment of leads.
