Nice Working Hurricane 350 650 Watts PEP Mobile HF Ham Radio Amplifier
This amplifier is tested and working!
I bench tested into a dummy load with ONLY 5-WATTS input from my Yaesu FT-817 and got over 100 watts out into my Bird 43 PEP wattmeter! (20 meters USB)
The last photo just shows the setup I used to test.
Seems to be all-original inside and looks nice and clean.
I cleaned the pots and switches with De-Oxit.
Shows some wear from being installed mobile but nothing indicative of damage or abuse. The front panel shows some fading. 
73 and Thanks for looking!
