Default Re: Grundig Concert Boy 1100 (again)

Thanks for the tips, I'll try them when I'm back next week. I checked all the electrolytic caps with an LCR meter and all bar one were OK. Are the two output transistors meant to be a matched pair? I only have a simple transistor checker on a DMM so no idea on test collector current.
