[Milsurplus] R-1051 "conversion"

[Bob Camp]

Hi

Another whole way to go at audio is to just drop in any of the modern  
audio amplifier IC's. They are cheap, easy to use, and simple to hack  
into a small space. The result wouldn't be the least bit "original"  
but it probably would work just fine.
