I got a hold of a really beat up Technics Co-deck RS-M1, a japan exclusive cassette player. It had heavily corroded battery terminals and just really dirty inside and out. I have finished adding my own battery terminals and all that and it works! (The 6v dc input works too!) Only thing left is probably a recap on a capacitor that deals with audio output as it is very sensitive to aux cord movement, finding the cap should be easy with the good ol pen trick! if anyone knows if a service manual exists please let me know!
