Parasound John Curl Designed Amp THX 5-Channel HCA-2205A Amplifier near San Francisco, CA..................

This is an offering for a Parasound HCA-2205A amplifier.

The 2205A is physically challenged, but without issue operationally. There are several scratches on the rack handles, a few on the face and a few on top. As well, two of the LEVEL ADJUSTMENT KNOBS are missing, ONE is LOOSE. This isn't an issue unless you need to adjust them from other than all the way up. The POTS themselves are fine. We always had them all the way up and adjusted VOLUME LEVELS within the processor. A stock power cord will be included.
