3. Description/Condition:
I bought this amp from Steve Miller used. The heatsink has some scratches on it. It was like this when I bought it, and it doesn't effect the amp in any way.. I had to rethread 2 of the speakerwire inputs do to previous owner , but they work just fine. The heatsink is from the 1st line of rd5750's which used to be called rd5000.1D. They are the same amp. I had it repaired about a year ago and have since run it strapped with another 5750.1 with no problems.. If you keep this amp supplied with plenty of current, you should have no problem running it well below 1 ohm.. I ran it a .5 ohm daily, with a DC Power alt and 7 batteries.
