RE: The Most Powerful Tube Amplifier Ever Built
Posted by LinuxGuru on November 2, 2009 at 12:35:40:
I have seen in Russian radio magazine 1200W tube amplifier with GU81M output stage and 3.5kV B+ voltage. Output transformer size is 26x36 sm. Fillament current for each GU81M is 11.5A. A real MONSTER !
