Hi, Amplifierguru,

You're so misterious. Could you tell who you are, what commercial products have you developed (in past years)?

[amplifierguru]

I have been designing amplifiers since a teenager and commercially on and off for the last 30 years, beginning with my own company in Australia in 1974 fresh out of a B.Sc. Physics. It was back then I was given the nickname amplifier guru - hope it doesn't offend. Audio Design made amplifiers,mixers, active crossovers and loudspeakers. I designed complete sound reinforcement systems using these products.

I don't know if this is the place to post my resume and besides some of it is commercial in confidence. But I did design the Eidetic (OPA627) chip driven MOSFET amps in Australia in 1989-94 - that have become collectors items, and I redesigned the amplifier range for Magnet in Thailand in 95 just prior to their successful JV with a US company, and worked as a consultant for a well known high end amplifier manufacturer in Conneticut!

I have also supervised/managed a turnkey installation of PA, theatre,conference, MATV and security in a palace in the ME.

I had published an article called Distorting Power Supplies all about PSRR - in Wireless World.

Cheers.

Incidentally, my dad left a catalina in a crate in Bandung after the war, don't suppose it's still there? Never picked it up.

Amplifierguru,

Thanks for the explenation. Hope you can submit some of your good power amp designs here (ones you dont hold secret to..)

Mikeks,

To me, you're a misterious figure too

[amplifierguru]

Mikeks, It was the Wireless World reference that gave it away, yes?

The article was headlined as " Audio Distortion - Holy Grail located" on the cover!

actually it was D.Self's reference to your article in his own publication...'sound MOSFET design'...Never got round to reading yours...
