Right channel seems to have died on Kriesler stereo - need help

[scientificexp]

I have an old Kriesler Q4 Disc-O-Tape from 1976. I've had it since 1992, and its always been excellent, and has always given me beautiful sound. However, in 2003 i stopped using it after the right channel somehow died. Like, it turns on and everything, and the left channel works fine, but the sound that does come from the right channel is REALLY quiet. I've tried swapping the speakers around, to check for a dodgy speaker, and it has the same issue even when i'm using headphones. I opened it up just tonight to have a look for any fuses or anything like that, but there doesn't seem to be any in there. Does anyone have any idea as to how to go about fixing this? Its probably nowhere near as good as the monster systems you guys have, but its a really nice sounding system, and i'd really like to get it going properly again.

Thanks in advance

Seems like a bad soldering or that your output is dead
