FAULTY!!!
There is a hum/buzz at the speakers even with no source connected.
I replaced a few caps hoping that it would fix the issue but it hasn’t and I thought the caps wouldn’t be at there best anyway .
The amp itself is in lovely condition.
You’re more than welcome to come and see it ( test it ) for yourself but my motto is “ snooze you lose “

its usually the big reservoir caps that cause that on these. think they are replaced with 10k microfarad ones. not much else should cause it

think they are 4700 in there but if you can fit bigger ones, all the better. height is the main issue. tricky bit is getting the panel out

yup... more the merrier. thats a decent amount. these amps usually hum for a few secs as they charge the caps but should be quiet then. maybe 5 secs. not sure about the voltage. had a feeling 35v was best, but cant remember

25v on a Naim Power amp caps is very low, I would proceed with caution. The only image I can find with google have 40v rated caps

Hi Mark , The 25v ones are the original https://uploads.tapatalk-cdn.com/20180602/3c3075e2f18c345ada6a08d28780954e.heic

I’ll stand corrected, only got a Nait 1 and experience with other Naim amps and caps my 1st thought 25v was a little low.
