[TenTec] Omni V audio distortion

[Martin Sole]

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?
