Are you aware how old and low spec that IC is?, it's only about 3W or something - you can't find datasheets because it long predates the internet or PDF files (or IBM DOS PC's).
I've still got a few here at work, we used to replace them in cheap record players - but even these (30 years or so old?) aren't the original ones, these have square fins, rather than the original fan shaped ones.
A short while ago I got a few of these, and they are the ones with the fan-shaped cooling fin. All I could find were the "Cricklewood-specs". So it looked interesting to me to find out more.
So, Nigel, if you have more information I would be glad if you could please me no matter how old they are.

I may be able to find a circuit diagram that uses them, most cheap mono or stereo record players used them - there was a 76003 as well (or something like that), if I recall correctly one had external gain components, the other was preset internally.
Well the specs have already been mentioned above, and even a diagram posted - I see the 33 is the one with external gain components. Here's a 013 circuit with has internal gain setting components.
Hmmmmmm indeed.
I have my doubts about pin 14, and pin 16 can't be found at all on the SN76033 schematic.
But it is worth putting on file. Thank you for another part of the puzzle.
