Power Amplifier Longevity

Hi All, 
I am venturing into the separate component world and was wondering how long a good power amp typically lasts.  I may have access to some older Lexicon CX and LX series amplifiers.  However, since they are discontinued and nearly 20 years old from what I understand, should I be concerned with how much longer they will last?  If they do need servicing, is this something that is available at a reasonable cost?  Or should I invest in newer equipment?

Budget is a concern for me which is why I am interested in these older (higher quality) amps at a reduced price versus spending the same amount on something newer, but lower quality.

At this time, I have a Marantz AV8802A and Vienna Acoustics speakers. 
Main L/R - Mozart Grand
Center - Maestro Grand
4 Surrounds - Waltz Grand

I thank you in advance for any advice provided on this subject.
Brian

Theta the only good maker of AV equipment? Really? Trinnov? Hello?

Doubling the voltage will NOT halve the capacitance.  Where did you get that from ?

Show me ONE graph that shows this.

Show me one piece of information in the following that indicates reduction of capacitance with its voltage rating:

Remember I am talking max voltage RATING not the voltage APPLIED.

As for inrush current limiters, MOST devices sold today do **NOT** have such current limiters.
All of our equipment has had current inrush limiters installed, going back 45 years. We did this to protect the AC power switches and over the years its worked out pretty well.
