If my memory serves me correct the main amp section used a pair of
4-400A's in the final and a pair of 810's in the modulator section.
The pictures show that this was built like a battle ship. For high
level AM you needed about 20 watt carrier and 10 watts of audio. Dead
key about 750 watts plate modulated AM signal. At one time that deck
was as powerfull as some broadcast AM stations at night.

Definitely heavy with the steel desk attachment.
