Default Sonos 1 speaker

Hey! Completely new to this but Iíve got an old Roberts R707 thatís in pretty good condition but doesnít work (just picks up white noise). I donít really listen to much radio but love the look and feel of the unit. Originally I thought of trying to convert it to a Bluetooth speaker, which Iíll still look to do if needed.

However I got a bit of a brainwave and thought about going a step further and breaking up an old Sonos 1 speaker and possibly turning it into a WiFi speaker?
Iím a complete novice so donít know if itís even possible but more than willing to give it a bash and try.

Wasn't there something several months ago about Sonos not only ceasing support of their earlier stuff, but also of bricking them?

It might be less frustrating and a better long term bet to look at some alternative.

Sonos withdrew the bricking proposal after a storm of negative publicity. They just don't provide any software updates.

I wonder if you could use the Roberts case and fit something based on a Raspberry pi or Arduino based board as they seem to be popular and provide genuine hi fi results from their DACs and soundcards.
I have no idea how you'd do it but I bet there's a fair few here who could.

The fault with the Roberts is likely to be just the usual problem the AF115/116/117 type transistors. Just identify the 'screen' lead on each of them and snip it off with side cutters and it'll likely start working again - easy!

True, but getting into the module that houses them isn't a minor exercise.

No, it isn't, it's an absolute mission to get the module out. If you do decide to do it, take plenty of photographs along the way! Definitely not easy!

Fair point, but what I meant was that it would be easy in the way that you wouldn't need any fault finding skills.

So I just pulled one out of a scrapper and you would actually have to remove each transistor from the module board to cut its screen lead, due to there being no clearance beneath them. Most people replace the transistors with different types, but just removing the screens should do the trick in most cases. If there's plenty of white noise, then it's likely to be one or all of the AF117s.

Its easy if you've got good practical skills is what I should have said - you'll need a solder sucker as well as an iron.
