I will buy all the boatanchor crap 1594A and 1594B you can get me.

For me, I have an app where I use some of the amp "differently purposed".

Not a particularly good amp as designed.

You must be trying to use the 70 volt transformer. Some have tried to use the 70 volt transformers from both the 1590 and 1594. The power transformers are not of any value. If I run across some 1594's I'll let you know.

no not the 70volt... and have to be A or B not later... do they all have a 70v secondary? I have forgotten now.

wow thanks for all the terrific input ! so to speak ,, really helpful ok so i should input a normal pre out signal from my av reciever or a pre amp. on taps 3 and 4 with the expensive relatively useless transformers in place.............excellent, as for what im doing with the amps i think they might drive a couple of 4 ohm subs quite nicely ! and very cheaply, the literature states they are designed for constant use .and the build quality is well ..i think solid ,,,would be an understatement i think my plan will work nicely ..i would love to go to the local swap meet or pawn shop and buy cool gear whenever i needed it but i dont live in north carolina anymore ! i now live in cancun and good gear is scarce to none..for hi fi stuff! im waiting on 6 sd 424 transistors to come in the mail and i will get them both going and let ya know what happens , these amps came out of a local disco and they werent used for any nautical purposes! and they only cost me about 60 bucks so what the heck!

"the 12 volt battery charger part of the amp "

Battery supply required is 24V~28V, not 12V. It does not charge the external battery, although you could modify it to do so.

Raw supply is 31V DC.

well these amps have some words stamped above the battery taps that state-, 12 volt charge rate 2amperes...............what else could this .mean.i take it to mean that the battery backup usually 2 12 volt batteries are constantly charging so in the event of a power failure current is taken from the batteries. in a freshly charged state. maybe im wrong but that is what it looks like!
