Parasound 2200 MKI

embrown057 · 10th March 2012, 04:38 AM

I have a Parasound 2200 MKI with the famous "bad relay". The left channel relay in this unit has an open coil, right side is fine for now. I still would like to replace both relays. The original replays are made by Koike electric part number HDI-48D-04. A simple 30A 48v SPST, PC mount. I would like to find a "drop in replacement" if possible to avoid mucking up the unit. My question is has anyone found a direct replacement for the relays or are they just wiring them up and mounting them to the chassis. I was going to call Tony at Parasound on Monday and see if he had any source but some here may have already been through this as this seems to be a common problem with this amp.

I guess I’ll amend this myself. Speaker relays are available from Parasound, just call Tony. Also to clear up any question on the setting I’ve included the offset and bias adjustments.

Not interested in selling this amp as is are you? I just need a single channel for my center speaker as I have a working HCA2200II for my L/R speakers. Thanks. Zac.
