Try looking for designs using TBA120, or SO42P, the latter is the Telefunken equivalent but some articles are in German so easier to find using that part number.? I think that you may also be able to us MC1330, but that's going from a very old (rusty) memory.
I'm waiting for my UBitX,, in a bag somewhere maybe in the UK, but on its way.
