[Icom] IC-751A - failure of audio related capacitors

Does anyone have the procedure for replacing the audio related capacitors in
the IC-751A.  I don't currently have a problem with my IC-751A but the other
day I was in an Ham Radio Outlet (admiring the 756PROII) and asked the
representative what his perceptions were about the IC-751A.  He advised me
that, although the IC-751A is highly reliable in his opinion, his perception
of the most common failure in the IC-751A involves the capacitors related to
the audio (both tx and rx). He said the symptom is distorted audio on both
tx and rx.

So I would like to know how to address the situation when/if the failure of
these caps happens in my IC-751A.  Does anyone have advice on how to deal
with this situation if it should occur?

Regards

I forgot to mention, my 751A still has the original VCO caps in it. Works
fine. use it every day.
