Hi,
I'm sure I read something similar to this recently but I can't locate it
now. I think the discussion centered on failing capacitors on the audio
board. Anyway my problem here is that I have started to hear quite high
levels of distortion on the received audio of my Omni V. Looking with a
scope and using a nice big wire wound 10 resistor as a load on the
external speaker output with scope across it I see clipping of the
negative peaks once they reach about 2.5v peak. Positive peaks can go
much much higher before clipping, around 7v. I would expect to see a bit
more symmetry.
The fixed level of audio out is clean so I think everything prior to C37
should be okay. From there the audio circuit is simple, if not crude, a
TDA1015 with a simple tone control between sections.
So, a leaky capacitor?
Cheers
Martin, HS0ZED
