Is age bad for solid state amps?

Thanks to every one.
I have a pair of ML CLS IIz stats driven as I wrote, by an ARC D200 amplifier.
I like the tube-sound of my solid state amp, but I heard so many positive comments of the 100.2 that I think it will have the same sound character of mine, but quite better in every aspect.
Then I heard something about deterioration of capacitors and transistors with age.
For my budget, a used 100.2 or a Sanders ESL amp (specially designed for stats), are the two options in my mind.
The Sanders (not the Inner Sound), is more recent but as I know this amp doesn’t have tube-like sound. So my thoughts were more on the 100.2
The problem is that I live in Mexico and would be a blind purchase in Audiogon.
So seeing your answers, maybe a more recent ESL Amp will be a better choice. I don’t know.
Also George Sanders said that tubes are not very good for electrostats, because they have bigger impedance than the speakers.
Buy the way, I cannot afford the exception: the Wolcott amp.
Thanks again and best regards

Your ML will need servicing before the amplifiers .....

Cinequadom - Transistors don't age or deteriorate. The only other component I know (other than tubes) that deteriorate is switch.

I’m new in Audiogon and I was answering one by one to all the replies in the order that were wrote; I was in the third answer when I saw that one response can be for everyone.

Bdgregory (the fourth): If that manufacturer is right, I need to replace electrolytic caps of a total of 130,000 mfd. probably the cost will increase too much.

Schipo: Your answer is very logical. We have a saying in Spanish: Todo por servir se acaba. I think is something like this: Everything for serving ends.

Unsound: You are right. But I think there is no longer an audio Research dealer in Mexico.

Elizabeth: As I wrote, my concerns are more about transistors than caps. As I know, these devices are very different between them, even if they come from the same production line.
So, High End manufacturers of solid state amps, place the output transistors to work at their extreme for 6 months or more; then match all of them to each amplifier. So, if one transistor breaks, the replacement if it is found is not going to match with the rest.
If deterioration of transistors occurs with age, a mismatch is logical.
And I think there is no dealer in my country.

Inna: Maybe you are right about ARC, but the same problem without a dealer.

Raquel: You are right about tubes, but as I wrote, maybe are not the best to match the stats as George Sanders said.

Wolf: I appreciate your advice. After all, maybe is not a bad idea the 100.2 especially for the cost.

Tmsorosk: As I wrote, maybe we don’t notice the lost of quality after many years of probably very slow deterioration.

Kijanki: I have heard exactly what you said about long time storage electrolytic caps and how to restore them. My amps are in use since I purchased them and run warm not hot.

Weseixas: Thanks, my ML stats have new panels.

Kijanki: Is so complex all this. Someone posted in Audioasylum that with age, transistors have small leaks between their elements. I’m confused.

Thanks again to everybody.

Nelson Pass re: the Pass Aleph O's:"...The amplifier does not need any maintenance. While the design in conservative, this is a hard running amplifier, as single ended Class A is the lease efficient operating mode. In fifteen years the electrolytic power supply capacitors will get old. Depending on usage, you will begin to have semi-conductor and other failures between 10 and 50 years after date of manufacture. Later, the sun will cool to a white dwarf, and after that the universe will experience heat death..."

I think it's fair to say that the Audio Research amp your considering will not be as "hard running" as Nelson's single ended Class A design.
