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.  All manufactured by ETO.
Alpha is currently owned by Alpha RF Systems.
They are still producing the ball busting Alpha 9500 auto tune amp based on the 8877 and two other amps.
The Alpha web site still has a very nice page devoted to the legacy amps
 Here is the link to their web site:
