I lucky, or do you have similar experiences?

I was surprised to learn that my Linn electronic crossover required
more
than one hundred fifty replacement capacitors. Then I found my Linn amp
needed a similar action when I plugged in the newly repaired crossover.

The capacitors on my LP12 power supply died a couple of years back. I
wonder if these Linn capacitor failures are a coincidence.


**Read the specs on capacitors sometime. It's quite scarey. Electrolytic
caps are usually rated to XXXX hrs @ 85oC or 105oC. The better the cap,
the
more hours and the higher the temp. Naturally, the cap is derated, as the
temperature rises. A typical cap found in a domestic product would be
rated
for around 5,000 hours @ 85oC. A mil-spec cap might be typically 20,000
hours @ 105oC. The difference in cost would be substantial. Keep your
caps
cool. Fan cooling is best.

My repairman used mil-spec replacements for about the same price Linn
would have charged to renew the original parts.

**That'd be about right.


I think I'll go turn off some amps now.

**Good idea. And next time some idiot tells you to keep your amp switched
on, send them the repair bill.
