I am trying to compile a list from my memory of the amp companies lost due the activities of the Hi-Fi mafia (and government created recessions) during the 80's and 90's. There may be mistakes, and I know a couple have been taken over as shadows of their former products. I will do similar list of T/T and speaker companies.

Anyway - additions and corrections please

Albarry
Aura
Exposure
Incatech
Magnum
Myryad
Myst
Onix

Really we should also add Quad to this list.
