Parasound HCA-1000A Modifications

I recently completed some modifications to my Parasound HCA-1000A a few weeks ago, and HOLY COW!!! Now my $300 amplifier sounds like I spent easily 10 times that amount. It's amazing what can be done with a stock amplifier--especially one as good as the HCA-1000A.

Anyway, my question is this: I am thinking about writing a manual about modifying the HCA-1000A and offering it for a small fee--maybe even putting together a "kit" containing the manual and all necessary parts. Would anybody out there be interested in such a manual or kit, or should I not waste my time?

This reply is for Avilex or Johnss. Though this thread is old I might have one of your modified amps. The 1000A I have has solen caps, silver wiring, dampning of the chassis and top plate, the loop rca's disconnected and volume pots have been removed. The previous owner did not know who did the mods. I stumbled on this thread while copying a review. If any of the names mentioned performed the excellent mods on my amp please let me know. I can provide pics to further id the mods done. Happy listening!

I am in need of a faceplate for a Parasound HCA-500 amp. Does anyone have one of these for sale or know where I could get one?

A older thread yes but these older parasound amps are special and I'm certain with mods there even better. I also have the HCA-1000a and a HCA-800 that I upgraded my self with all new Nichicon caps. Wasn't expensive at all and made an Audible improvement plus extended the life of the amp. Still have both amps and I am enjoying them. It is important that you keep the replacement caps at the same values except you can use a cap that is rated at a higher voltage but the capacitance should be as close to the same. Only use exact replacement caps and pay attention to whether they are non polarized caps or polarized caps.
