Thanks for the responses guys, I am learning!
Let me clarify as to why I had posted the message asking about the capacitors drying out. Last weekend I was trying out a few amps which were old and although they all sounded different, some were not sounding satisfactory. All those amps were between 10 and 20 years old.
I spent the entire Sunday hooking them up and after conditioning of say about an hour or so, did some critical listening. One of the amps was a real disappointment and that was a Marantz PM-94 140 watts/ch quarter of which was Class A (1988) . This amp has garnered cult following having a dedicated website and some consider it to be the best from Marantz. I was very curious to find out what the sound quality was like since I had owned one of the Marantz amps (PM-80) in the early 90s which also offered 25 watts in Class A mode. This amp was nowhere sounding as good as it should on the bases of what I had read about it and my memory of the one I owned. The bass was loose and sounding boomy, the overall presentation was nothing to write home about. I thought that this performance just cannot be and there has to be an explanation as to why it sounded so mediocre This actually made me think about the capacitor problem having read here on Agon as well as other sites, hence this thread.
