I'm trying to find either a reliable source for a TDA1085 Ic or a
direct replacement. Failing that a functionally equivalent device.

See:

That shows 59 vendors, mostly in China, that have some level of
inventory. Buy a few samples from a few of these vendors and ask them
for a quote on supplying your unspecified required amount. You'll be
surprised that many of them have literally thousands of parts in
inventory. Be prepared to haggle over the price.

Also, don't believe most of what they say and promise. Cover your
posterior by ordering from at least 2 vendors at the same time. Even
the largest US vendors are not 100% reliable, so you might find it
useful to disclose which aspect of reliability (price, delivery,
quality, support, credit, shipping time, inventory, etc) you find
important.

I couldn't find an exact replacement or equivalent. However, you
might skim the data sheets for "related" parts found near the bottom
of the page:
