Representing Joel Kennedy who happened to repair a Hafler

240SE P.A. amp that nobody but nobody else could repair. His

background in electronics repair and design of speakers and

audio was obvious after one visit. I was referred to him by a

a professional friend, who retrofits machine tools. The two had

previously cooperated in designing an unusual amplifier, and

since I knew a little about web pages and indexed search, I

offered to put up a web page to see if I could sell by internet and

manufacture their design. We are a small group of independent

technology hard core devotees applying our brand of science

outside of our usual work a day jobs and lives and have enjoyed

bringing ideas and doing many experiments using the internet.

I have bought this amp and work with it myself. I play guitar.
