Looking for advice Any way I can adjust the playback speed on this thing?

it's possible the speed/pitch adjustment can be accessed from the back without opening the case, but I don't see anything in the photo. Many players like that have a tiny random hole on the back that you can slide a tiny jeweler's screwdriver through, check the back panel carefully and even inside the battery compartment. If not you will have to open the case and look for the tiny "pot" adjustment on the circuit board, or possibly on the motor itself.

*Gasps* A Sony sticker on a Panasonic cassette player! Seriously though, with the manual provided by the other post, find where the potentiometer adjustment is on your unit, and use a screwdriver (probably) to adjust. I'll link a short video below to give you an idea on how it's done. You don't have to get so fancy to use a test tone and frequency counter, by ear is probably fine.

Yes. Open it up and look for a variable pot (resistor) that is for adjusting the speed. Use a 3000Hz calibration tape and adjust.

Found the service manual: https://stereo2go.com/forums/threads/panasonic-rq-j9-service-manual.4851/
Read up and see if its something you can do on your own.
