Nap 500 doesn’t stay on

This is related to the spring on/off issue that I there have spoken about as well - and folks have fixed it too apparently.

I’ll eventually have to get it shipped for part replacement - but bad timing right now - since Christmas/new years - and it’ll probabably be two weeks shipping each way + a month of so at HQ in NYC.

So - can some in naim tech support tell me if it’s a simple slip issue or is there a part that’s worn out? When I fiddle witht the spring, and push it in a little, I can turn it on and it stays on. But when I switch it off - its back to square one.

I fiddled with the spring and can make it turn ‘on’ but when I turn it back off and back on it doesn’t stick.

Unit is powered off - no worries about that.

This seems to be a common issue and has been occurring for many years. I am surprised that Naim has not a resolved it or maybe they have on newer kit?

This is fairly new kit - about 7 years old - not 25…

Something doesn’t look right with the spring ….?too tight
Try prying up the spring and see what happens

I was hoping someone had a picture of what a healthy spring in this unit looked like..

For now, I’ve managed to turn it on: and will reinstall. Will ask naim to let me know when they’ll be ready to work on it so I can ship with minimal downtime.

As David said, use some pliers and open out that top spring.

I’ll do that next time I have to turn the amp Off/on. It’s playing again now..

You should be able to source a replacement switch for less than £10 online, not that hard to swap out.

@Richard.Dane has forcefully an idea on that.

The more recent switches from the last decade or so are a little different I notice and seem to be more recessed/flush with the fascia compared to earlier Classic kit, and require a push further into the recess in order to latch. I would guess the original supply ceased so a different switch had to be sourced?

Anyway, the old faithful trick to getting a switch that’s reluctant to latch to eventually latch more reliably is to exercise it fairly rigorously with the eraser end of a pencil until it begins to latch consistently. Obviously only do this with the unit unplugged from the mains.
