    Parasound HCA-1203A Power Supply Size/Capacitance Question

    I know it is a very old model but does anyone know of any reviews or know the specifications of the HCA-1203A? There seems to be conflicting information concerning the size of the power transformer and the capacitance of this model as the manual states 1Kva and 60,000uF where as the specs on the website show 1.5Kva and 90,000uF. Anyone know for sure or checked the insides or anything. I checked inside mine but can't see the writing on the caps at all as they are all facing the wrong way. The information on the web on this amp seems pretty scarce. I even emailed Parasound support and they didn't know the specs because they didn't have one around anymore. Thanks very much for any help.

    Does it matter?

    Since it's an old unit it may have lost 20-30% of the original capacitance due to age...

      See two threads down where a similar quesion was asked. Manufacturers make parts changes during the lifetime of an amp's production run all the time, whether due to parts availability or to make modest design improvements. The greater power supply capacity should result in a modest increase in headroom at best. Even if your power supply is the smaller version, there is nothing you can really do about it. Just enjoy your amp and quit worrying.
