Sanken Hybrid Audio Power Amplifier Data

NOTE!

These amplifier devices have been out of production for >20 years!
 You cannot use them for new projects unless you already have them!
They are no longer available anywhere I know of. 
Flash!: Barry Sloan has one SI-1030 for sale at

There are several modern successors so these single-package
audio power amplifier modules.  For example here are some...

Series SI-1000G

Sanken series SI-1000G amplifiers are self-contained power hybrid amplifiers designed for Hi-Fi,
stereo, musical instruments, public address systems and other audio applications. The amplifiers
have quasi-complimentary class B output. The circuit employs flip-chip transistors with high
reliability and passivated chip power transistors with excellent secondary breakdown strength.
Built-in current limiting is provided for SI-1050G and all devices can be operated from a single
or split power supply.
