Parasound HCA-2200II Upgrade

[bigskyaudio]

Our audio shop has closed due to retirement and I would like to share our mod for the HCA-2200II. The only person we have ever shared this with was John Curl many years ago. I hope that this will help some of you who would like a little better sound quality but the mod will improve clarity first and foremost.

Thank you very much! I bought the amp a couple years ago but did not get a chance to send it to you for the mods. Would you happen to have a parts kit for the mod that I can purchase? Thanks again for the info.

Hello,
For some reason I am not able to open the attachment or see if a parts kit is available. Do you still have this information?
Thank you.

The pdf file opens just fine for me.

Not surprised at only updating a few parts. That was/is a fine amp. Had a couple of them. hey were overkill though and the modifications John led me to on my MOSFET I still am running.
