Is 1000 hours for lifespan a bit on the low side?

Very low hours.

doggiehowser.......I don't concern myself much about hours before failure since those hours can be doubled, even quadrupled by purchasing caps with higher temperature ratings and higher voltage ratings as commented by Tom in post #108.

Hey Dan,
My f110 went belly-up on me last night and I just want to make sure I'm getting the right capacitors. You have the f113 so are these the same capacitors I should get for my f110? Thanks!

Photoboy.......I suggest you pull the amp first and look at the capacitors highlighted by the arrows in my f113 amplifier photos. The auto on sensing circuit where the small capacitor is shown by the red arrow is probably your suspect part. Check to see what value it is. It is most likely a 100uf/35volt/85C cap. If so the replace it with the one I ordered, a 100uf/35volt/105C cap. The larger 400 volt cap shown with the yellow arrow may not require replacement. Mine did not.

Thanks Dan. I was never good at understanding electronics but I do know how to follow directions. The info you've provided is awesome.

[jdandy]

Photoboy.......Hopefully this information will help you get your f110 up and running again in a jiffy.

We had an incident here on Cape Cod last month with the electric. The AC motor boated; turned on & off very rapidly, about 5 or 6 times in succession. Not even off long enough for a back up generator to turn on, and help.

All of my gear was perfect (some systems were even playing). One F113v2 wasn’t as lucky; it was producing a rather high pitched signal for a sub, at a fairly loud level. The sub was in standby mode.

JL Audio tech support was familiar with the issue; it was a Transistor and a few other components.

They had me measure the impedance of the driver, to verify it was ok. It measured 2.4 ohms (well in the safe zone)

I sent the Amp plate, and the internal crossover (requested by them) for warranty repair. I received it back in about a week, and all is fine once again.

JL does recommend keeping the sub on at all times, as opposed to signal sensing mode.
