Hi all,

Here's another dog. This set has blown every vertical output IC that I've
installed. The oem parts last longer, but not by much.

Besides the IC (IC550), I've changed C559, & D550. I've also checked that
the 27V supply was not running high.

I'm hoping that someone out there has already tamed this beast.

Opinions?
