One of my ZonePlayer ZP120s has started buzzing and crackling through the speakers.

I’ve swapped it with my other one and there is no fault and the faulty one connected to the good ones speakers has the buzzing fault so it’s the amp itself that is faulty.

I’m in the UK is the Amp repairable locally or does it have to be returned to Zonos in the USA?
Can I buy a new one my system is still gen one, so i’d need a compatible product.

SONOS does not offer repair services anywhere on the planet. I’m in the USA, but I understand that there are 3rd party repair services available in the UK and EU.

ZP120 can be replaced with a SONOS AMP.

Ebay and the like have a good selection of older Sonos devices for sale. 

Confirm the status (working, broken, untested) and the date of manufacture.

Devices that have a 30% upgrade option available may sell for more than a similar one that doesn't, it is worth asking if it is not mentioned.

ZP120 can be replaced with a SONOS AMP.

Thanks for your replies and help, I put in online search “ 3rd party repair services available in the UK” and there’s a one only 20 miles from me so good result thank you.

Update

I emailed the company (https://sonosrepair.co.uk/)

Hi could I bring you my ZP120  to have a look at please?
 
I have two,  One has started buzzing and crackling through the speakers.
I’ve swapped it with my other one and there is no fault evident and the faulty one connected to the good ones speakers has the buzzing fault so looks like it’s the amp itself that is faulty.

Got the following reply.

Good afternoon Jeff, 

Thanks for getting in touch. 
We repair many Sonos ZP120 device’s with similar faults 
We will happily assess and if possible repair yours- we do operate a no fix no fee service 
There’s a link on our site to organise return shipping labels if you would like to go ahead with the repair
Best regards 
Natalie 
 
But in the meantime I decided to travel to the address on the website and see if I could just hand it to them to have a look at.
 
On arriving I found an unoccupied house with a boarded up double garage, outside of which there two were piles of broken electronic components some of which were clearly Sonos.
 
I emailed them again informing them I had visited and described what I found and I have heard nothing back from them.
 
I found a telephone number but there was no answer on that either.
 
There is a option on the website to book in your repair but you have to pay £19.99 up front

Payment covers shipping both ways and covers our initial repair assessment. 

You can drop your parcel at the post office or have it collected.

We will Email your labels to you (usually within 2 to 3 days). 

From what I’ve experienced up to now I won’t be paying them anything and I would warn anyone who lives too far away to visit to be very wary before paying out money up front to this website.

you could buy a second hand one from Cex for £60.00 grade B it even comes with a 5 year warranty

I brought 2 Play 3 off them grade B and they seemed in prefect condition just no box

also don’t forget to activate you Sonos upgrade discount 30% on the old one

Thank you very helpful I’ll check it out.

Don’t forget that some older Sonos is only compatible with S1 and not S2 and some is compatible with both

Thanks k1elec I’ve checked out the comparison and looks like the zp120 uses a different protocol so I’ll go for another 120 from Cex but thank you for your offer

Ok

Update 2 Got a ZP120 from CeX £60 works perfectly with a 5 year guarrantee

Also sold them an old ZP80 I hadn’t used for years for £22 so worked out I only paid £38!

Good result thanks for the link k1elec
