I hate to do this, but both of my Zed-built US Acoustics USA6300 amps are for sale. I'm still going with US Acoustics in my system, but in a different configuration. One of these amps is in average condition for one it's age, with some chips and scrapes. It functions great, has a new set of plastic mounting feet, and a nice set of terminal screws.
The second one is ugly. It has heavy chips and scrapes in the paint, and some aluminum is worn off a couple of the fins on the heat sink. One mounting tab has been cut off each end of the baseplate (with a torch), and the slag needs to be ground off these cuts to use the mounting feet. I polished the scorch marks (from the torch) off the end plates, so they look good. Internally it's pristine, and works as well as the nicer looking one.
RMS, per channel @ 4 Ohms @ 12.9v: 50W x 4 + 65W x 2
RMS, per channel @ 2 Ohms@ 12.9v: 75W x 4 + 80W x 2
Channels 5 and 6 only: 150W x 2 into 1 Ohm or 300W x 1 into 2 Ohms
Input Sensitivity 100mV - 8V
Slew Rate 20V / microsecond
Total Harmonic Distortion Less than 0.01%
S/N Ratio 104dB
Damping Factor Greater than 100
Phase Response Lagging 12 degrees @ 20KHz
Input Impedance 22K Ohm
Protection:
Reverse Polarity: Yes
Thermal: Yes
Short Circuit: Yes
DC: Yes
Idle Current: 1.0A
Fuse Rating: 25A x 2
Length: 15.3" (about 17" including the mounts and speaker terminals)
Width: 8.2"
Height: 1.9"
Weight 9.00 lbs
The nicer one is $150, and the ugly one is $130. The pair is $275. These prices include shipping via UPS ground within the CONUS. PM if you're interested.
