Unit is as seen in photos, it powers up, no music but has buzzing sounds out from the speakers. Don’t know what’s wrong with it. Selling as is for repairs only. Will be shipped the next business day with tracking #. Thank you!

Vintage Parasound HCA-750A High Current Power Amplifier with power cord as shown. This is in very nice shape cosmetically. I only have the power cord to it and can only test the AC Line to Standby to Normal lights on it. They appear to work fine. Please see photos and email with any questions. Thanks for looking.

This is a very high-end high current amplifier. That sounds absolutely amazing good specimen.

This is a very clean, outstanding sounding amplifier
