Nope, LM386 on the backside of the board (surface mount version of the LM386).
FWIW, K-line, Williams, maybe others, oh yeah, and drumroll- Aristo-craft all used those sound chips that I have put hands on.
Elan EM57P300CPS audio chip one time programmable.
And yes, you can swap them to try different sound sets depending on who and what was programmed into them.
Example in that aristo-craft live steam swap with a Williams steam chip
