Default Slide recording resolution

I would like to use a commercial service to record digital images to
transparencies, for use in a stereo viewer. Does anyone know what
typical resolution (PPI) these services record transparency slides at?

Minimum 300x300.

300 ppi resolution on a slide would be totally unacceptable for viewing.
That's OK for printing, but a slide is likely to be blown up 30, 40, 50
times. I would consider 3-4,000 ppi to be a more reasonable figure.
A good consumer film scanner will output 4K ppi.
A drum scanner will do even better.

Correct, I mis-read thinking he was digitizing slides.
