The 1593B and 1594B sound great!

I heard something about using 1588 preamp in the socket for the input transformer. Is it possible?
No, the 1594B octal socket is not wired to supply power for the 1588 mic preamps.Originally Posted by laperlestudio

Are these the amplifiers that can also be powered from a DC power source?

Drive in movies used battery backup...AFAIK all of the 70's solid state stuff, with the exception being the stereo amps, could be DC powered.
Honestly, I didn't work much with old tube stuff.
I used a solid state Altec to build a PA on a golf cart once...
Your neighbors called. They like your music.
Yep, 24VDC. The function was also used in emergency warning systems that had to work in an outage.

I did a rental one time for U.S. Congressman Jack Brooks from SE Texas - seems they wanted to break ground for a new county jail to be named after him, perhaps aptly, and they had no power to power a sound system.
I used:
(1) Altec 150B Bi-Acoustic Horns on tall stands
(1) Altec 1592B Mixer/Preamp
(1) Altec 1590B Power Amplifier
(1) Altec D654A Microphone
The 1592 and 1590 were powered with two 12-volt car batteries wired in series.
Worked fine, and the 150B's sounded GREAT!

Ouch! i was just looking at the DC current draw........................... and calculating how many cloudless days of solar collection it'll take for an hour of run time on a stereo pair with my current collection/storage scheme.
My current system is all 12 volt storage, but i can see 24 volt in the future and ultimately a pair of 1593's might not be out of the question.
This is a bit OT, but does anybody have any info, even from memory, on this little BGW?
