And if all else fails (or perhaps sooner) there is JJ at Amiga Center France. JJ did an amazing job on my A4000 and daughter card. I had no Par: and my sound was nearly gone...not to mention no battery backed clock since I pulled the battery.
JJ completely referbed the mob and daughter card, fixed all the port and sound issues, and installed a rechargeable battery. All for a very fair price. Worth the postage from California for sure! It's like having a brand new A4000!
