You can actaully get warrenties form ebay. http://pages.ebay.com/help/warranty/buyer_faqs.html
Don't know exaclty how good the service is or how good the fix is but its a warrenty none the less.
Thats the info. What kind of dc-dc converter are you talking about for the 7995. I would love a hu wih no internal amp but most are really expensive.
