1990 Olypmus Video Light Source - Noxious Smell
« on: March 22, 2014, 03:51:51 am »
I came upon a new appearing Olympus video-endoscope lightsource that I would like to use as a bore-scope.  Only problem is after a few minutes a really nauseating stink comes from the PSU fan.  Not your classic burn resistor, plastic but something I would expect (though never experienced) from that described for selenium rectifers that have become zapped.  I have looked over the chassis and it looks virtually new, no dust, no dead bugs, and no bulging or leaking lytics but it is definitely coming from the power supply PCB.  Should I just replace the 6 or so lytics or is there some other 1990 vintage culprit known to smell this bad?

thanks

jerry

If not caps, transistor, rotting rubber or plastic, or perhaps mice used to read the newspaper in there.

1990 electrolytics? I would change them to new ones. Thats 24 years of service life all ready. Very respectfull for any electrolytics.

While capacitors are out, you might consider use some sort of electronics cleaning spray or something, just in case of above mentioned reason...
Electronics, Linux, Programming, Science... im interested all of it...
