US Amps The Optimizer.

Item(s) Description/Condition:

It is basically a voltage regulator that outputs a steady 14.4v or 16v for your amplifiers, up to 100 amps. Made back in the late 90s/early 2000s, these are not easy to find. There are some hidden settings on the board, suggesting that this unit may be able to output more than 16v but it is set because no amps made back in the day can take anything higher. We all know how underrated these old school US Amps stuff are so I'm not surprised if this thing can be tweaked, but I never touched it.

Has about two hours of real use on it, powering some old school Proton amps. It is in very good condition besides some fingerprints and a couple of minor dings. It is missing one screw on the terminal (but that input is hooked up to the other two screws internally). The original box got wet but I saved the serial tag and the badge off the box.


$340 shipped/insured/tracked.

Not only that but it also regulates the output voltage so it'll be a steady 14.4v or 16v output even with the engine off and battery voltage sitting at 12.5v.
