snip.

Get the IC numbers off the board and you can get order them from
Andrews Electronics. Their number is 800-289-0300.

Also, I have seen the TC9273N-004 from Onkyo cheaper. Not sure about
the other. Their number is 800-229-1687. They can look up the
generic Toshiba numbers you gave - at least they've been able to
when I called on one before...

Got my replacement parts in no dice. One gets real warm. I'm
thinking this amp is screwed. I've only put about 30 bucks in parts
into it. I have no clue what else to look for.

I don't think those chips get warm normally. Could be one of the plus or
minus 15 volt lines is high. You could still have a blown channel, or a bad
voltage amp IC...
