ETO Alpha Amplifiers

After his early involvement with the Signal One line of transceivers Dick Ehrhorn went on to found Ehrhorn Technological Operations
 and began producing what are arguably the finest power amplifiers ever made.  I have four of these amps in my collection.
Alpha is currently owned by RF Concepts.
They are still producing the finest power amplifiers available including a ball busting auto tune amp based on the 8877.
