Wondering if any of you folks out there know of a source for a schematic for the YB400PE receiver. I've had no luck using Google.
My little Grundig croaked the other day and I'd like to try to repair it versus giving it the heave-ho.
Thanks for your time.

I hope you find it because ill need it some of these days.
