    They retail at $1300 and can be found for $799 each.

    I grabbed two of them just for testing on my metro and couldn't be more happy. I'm actually looking at some of the newer style boards either the 6.5kw or 8.5kw.

    Its a Zenon board that's used in... iirc old sundown saz3000, atomic at3000, Rd 3250.. ect.

    Still have yet to put it to a test but will try in the next few weeks.

    Price was right though.

    It does look like the old RD 3250. Dunno if 800$ is really a great deal on 3K.... that's about what I'd be trying to spend on AB500.1 or Atomic 5K, etc.

    I just made a new video and will upload soon.

    $800 new with warranty is alright.

    Anyways the test results are...

    Dropping to 11 volts
    AC voltage 57.7
    AC amperage 51.2
    Starting impedance 0.5 omh 1.12 ohm after rise
    For a total clamp power at 2950 watts @ 11 volts..? That's pretty decent and that's rated specs!
    SPL of 150.42dbs

    Not really underrated but not bad. I wouldn't want to drop $800 though.

    Re: KARSTADT amplifiers?

    I'd sell them for $599.

    I'm going to continue testing though, trying to keep voltage around 12 volts and see what happens.
