Default STK 4191 Datasheet

Well... I have an old amp (A Fischer Studio Standard) that for some reason one channel isn't working, perfect time to take it apart

So... inside is an STK4191 (not a V or II), I am going to be optimistic and assume that the it isn't broken because the whole unit is old and dusty so it could be anything. I haven't powered this thing on in years and it had power isolation (popping) issues anyway.

Now I need a datasheet so I can convert this part into something useful. I can't seem to find one on the net though. Anyone have a lead?

is a brief schematic.
Perform a search on the different other numbers from that family.

Woww, thank you both. The

The datasheet link is for a STK4191V, I think I found one of these last night also. I was worried that it wasn't the same pinout as the STK4191, but the two pictures seem consistent so I'll use that. Thanks!
