I purchased 2 of these off of ebay from private indaviduals. Both were used ,but in very fine shape. Now my use was a little different. I have a Marantz quad pre amp that is a beautiful vibtage unit. Geting or should i say finding 2 marantz 140 75 watt amp would have cost 1200-1500 dollars . have a speakercraft b2125 amp in my shop. It sounds great. So i have hooked up 2 bb275 amps to the pre amp ,hooked up 4 infinity 2 way speakers and nan what a beautiful sound. Loud as hell for 75 watts. I almost want to keep this my self. I am going to give it 2 mire weeks of tryout before i sell this quad set up. . this are fantastic amp .even used .the todil power supply is an expensice addition as pioneer has the patient on ths or did. And the high current output will play any music. A+for the speakwrcraft amps. Even used they kick ass. Pat b Audiogeeks vintage sales.

No volune contol on the amp itsef. The pre -amp has to control all the amp fuciobs. Not that that is realky bad. But i like contol o ny audio produxts.
