Phil,
Recent experience with the STK392 series of convergence ICs has been erratic
with generics. In particular, the -110s have been problematic. In the -0xx
series, you can upgrade to higher numbers in the second digit for greater
power ratings. I would use the Toshibas. Of the manufacturer sources they
have the best pricing and I have yet to have a bad one from them. No matter
what you use make sure that you deal with a company that will take back
defectives without a hassle and test the related circuits thoroughly. On
the Toshibas I have had a couple that had problems in the DCU that caused
the output to fail, and you always need to check the related power resistors
and electrolytics. I just check the convergence channels out of the DCU for
dc offset on all the Toshibas now, having had two that drove me nuts.
I use generics or other brand originals for most of the Sonys, BTW. I have
never had a problem with differences in performance and the pricing is
ridiculous.
