JL Audio 500/1 "Slash" Class D Mono Amplifier Repair

In this video, I repair a JL Audio Slash amplifier. It had blown the power section, one dead mosfet on the output section, a shorted op-amp, and a few other small parts. If you want more details on what I didn't show see this post www.diyaudio.c...

If you like these amplifier repairs, maybe I can do more. I would prefer to do multiple-part videos to explain the repair in a little deeper detail.

I had 2 of those amps and both have failed. Both were installed by pros, still have 1 of the broken ones collecting dust.
Nice job on the fixing it and giving it another life.

I have 2 also they work it's just my slope button is loose and it's not pushing like it should

Sent one of these out a long time ago, and the guy basically told me it couldn’t be repaired that the “mosfets” were shorted. That was ten years ago and I realize now I got ripped off. I’ve become better at circuit repair and could have done it myself at this point. Live and learn I guess but cool to see something I owned and had issues with in a repair video

Thanks for sharing that. Yeah I can empathize with that experience. I am glad you found some entertainment in seeing it fixed. These amplifiers were so popular. We all probably had one or knew someone with one. I remember my roommate having one of them when I was 18. He gave me my first amplifier for installing the JL in his blazer. It was a Kenwood, maybe a KAC line, that he gave me. I can't remember if I fixed it, but this isn't the first slash amplifier I worked on.

"Slasher" not Slash. I still have 500/1 from like High School. They were wildly underrated compared to other amps (output wise - not fanbase wise. Everybody knows JL is creme dela creme). They were probably the only "500" Amps that put out 500RMS. I had 1000 watt amps that barely did 550 lol

Never heard JL refer to them as "slasher," it was always the Slash series amps. Even in the new JD Series training, they referred to them as slash.

[@fatal_delusions]

It's definitely Slash, not "Slasher"

Sweet. Mine just quit tonight on the way home after nearly 20 years. Need to pull it out and open it up. Not sure if I want to take the time to fix it or if I should just grab a new JL amp. Appreciate the video and getting to see whats in there before I jump in..... if I end up doing it.

That's a damn shame I can't send you mine for repair. Can't find anyone to fix these things.

What is the value of the gate resistors and where to buy them

[@NoName-yr1jv]

Well done 👍

[@FixedUntilBroken]

Thank you. I'm glad you liked it

[@Bowhunter2500HD]

I have sent you a email

[@lt7518]
