Hi all.
Recently acquired a silver Sony Walkman WM-4. Installed new batteries, new belts and lubed gears. When pushing play sometimes it it will start and sometimes not. With the back off I can rotate the silver metal gear by hand and it will eventually begin to work. When it does come on the sound through the headphones sounds like your underwater. I can't seem to find any information showing where to adjust the speed on this model.
Thanks for any help or advice
