Is age bad for solid state amps?


Hi everybody,
I am interested in get an Audio Research 100.2 amplifier.
As I know, the production of these amps was from 1998 to 2003.
I wonder if transistors, capacitors and other electronic parts have some deterioration with age.
Thanks.

Greetings for everyone

The great thing about this forum is that we can learn a lot from people who have deeply knowledge of High End Audio.

Everyone agree that electrolytics have deterioration with age. But the first post of Kiyanki shows that caps of a temperate amplifier like mine or a 100.2 can last probably more than 20 years.

Elizabeth, Kiyanki and Unsound agree that transistors can last many, many years. I think now that they are right.

Raquel goes deeply and her last post shows that low impedance, heat and overload might be a problem for output transistors.
I don’t really think that would be an issue for amps from Audio Research, especially because my own good experience with this brand.

Also, the web site she placed is absolutely great.

The posts of Raquel make me think in something that was floating in my mind: tube amplifiers.

For less of $700.00 including shipping to my Country a YAQIN MC-100B KT88 Tube Amplifier could be a good option.
The unit has 65 watts ultralinear, 35 watts triode, two separated power supplies with their own transformers and can be used as integral or power amp.

I think 65 watts are not enough for my electrostats.

So the question is, if this amp can be bridged to double its power without any issue and if its output impedance can go at half or so and make a better match to my CLS,s.

If possible, a pair of NEW “monoblocks” is quite less costly than a not so old ARC 100.2 or a Sanders ESL amp and even I will get an authentic tube sound.

So, I need an advice again about this.
Thanks.

I forgot to place the web site of the Yaqin amp's seller.

Is aging a bad thing? Well, yeah - I have swelled-up and I leak a bit now and then. But I can still boogie, baby!
