Sorry it seems your post has been ignored.
Did you end up performing the cap fix? Its not that it will not work on the V1 amps.....V1 amps had some other issues in the output board that caused a hum.
Post 2513 is where you can download the instructions. order the parts from Parts Express. Find a local TV shop to do the work.
Just remember....lots of great subs out there in the 500USD range and most come with a warranty and some peace of mind!
