Here you can see the line of the Alpha Amplifiers.. Photo’s taken from the inside and outside. It’s one of the best Amp’s ever made.
First a few photo’s and details about the Alpha linear click on the front photo to view the details about the amp!!
Features
- Capable of 1.5kW continuous RF ouput on all commonly used modes and on any authorized amateur frequency from 1.8 to 29.7 MHz with no time limit
- Full CW Break-In (QSK) and all digital modes
- Compatibility with popular amateur transceivers and exciters
- AlphaMax firmware comes with added features to readjust output network, trim tune, and readjust loading to prevent distortion due to overdrive.
