Question about Audio Players & Recorders
The left channel on main front speakers isn't working. Is the op amp likely to have gone.
It could be the op amp, however there are other possibilities like:
- a bad speaker or a speaker cable (try some swapping, see if the left channel is still dead)
- a bad / damaged speaker connector or a bad solder contact on that same connector inside the unit
- a dirty / oxydized connector pin or a bad pin solder contact on any of the connectors inside the unit
- if the main volume pot is actually made of several pots stacked onto a common axis (unlike the standard stereo pots it will have more than six pins), see if any of the pins are poorly soldered and resolder if necessary, if it has a connector also check that for dirty contacts
These are just some of the possibilities so don't take anything for granted.
Hope you can find out what it is.

I just bought a 4240 and was upset for a half an hour until fearing my left channel was gone, only to discover the little Radio Shack bookshelve speakers from the eighties that sound awesome now has a bad speaker jack! Grabbed another speaker wire and another set of speakers and the sound is truly amazing. Once again the "Keep it simple stupid" slogan applies here. What a relief!
