Kevin,

             I have been repairing and upgrading the PS 90,75 and ICS sub amps for some time now 10
+ years. I realize your post is almost a year old and you may have found a solution. Just for your information and others looking for repair for these units. I also have some of the last remaining inventory for the upgraded digital boards and IR sensors. I can't offer a swap due to the limited supply of parts but can offer a repair/restoration of your existing unit. These are a well-designed amps but went through three revisions They still require revisions to maintain stability, all covered in the repair/restoration. 

I really need your help with my snells

Hello Ampman

 

I have these speakers and one of them is having major issues. I think there is something wrong with the circuit boards and tow back tweeters are working although the drivers are fine. Any solutions to fix these? I love these speakers. Also any idea where I can get an receiver fixed? When I first hooked up my onkio to these speakers some power surge occured and blew out a channel on my onkio
