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.Originally Posted by bowtie427ss

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?

so what do these things sound like. i'm thinking self powered a7s unless these are better suited for a PA system.

That's a lot of weight to add to an already large and heavy box. I have the A version which doesn't re-sell well due to some kind of positive ground design, that I don't understand. I'm not currently using them. I did use one for a short while, and thought it sounded fine. They were designed to directly replace the green vacuum tube amps that do sell for big bucks, currently. From what's been told to me on the board, the 1593, and 1594 sound pretty good...... the 200 watt 1590 doesn't have enough top end for HiFi.

is this the one you hooked up a cd player to?
what gets me is some of these amps show a 1% thd. isn't that a little high?
