Parasound HCA-750a. New Capacitors.

Hello. This is a wonderful sounding amplifier. Some of the capacitors had started to fail so like every other unit that I’ve owned that is over 20 years old, I replaced all of the capacitors with high end Nichicon “audio grade” caps. I’ve upgraded well over 100 pieces of audio equipment. This is an awesome sounding piece. Very good resolution and awesome bass. This amp is direct coupled with no coupling capacitors in the signal path. It is in overall very good condition with a few scratches here and there. Very presentable from an equipment rack. This presents an excellent value. To have the service done, it would probably cost $300 or more. I’m basically selling it at a price that reflects one in good condition without the upgrades.

Comes with a power cord. Let me know if you have any questions.
