Last one!

It there's anything I haven't captured or isn't clear enough, let me know - or I'll give you first refusal to buy it. :D

Excellent :D

Thank you for the scans and photos.

You have just about covered everything. Just one more showing the track side of the PCB looking at the solder connections of the bottom of the edge-connector, so that it is possible to see which tracks connect to that side of the edge-connector.

That is, the side of the edge-connector that is nearest the edge of the main PCB.

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb :!:
Looking forward to summer later in the year.

My Issue 2 is wired slightly differently to this but as posted earlier my images seem to have disappeared from the relevant post and as my zonx is now wired for stereo and is a bit of a pig to dismantle it's little stereo board and photograph both sides perhaps Rich could look into why my pics ( why maddeningly I didn't backup) have gone?

I only mention this as it was suggested in an earlier post that something other than an issue 5 might be worth looking at.

Alas, I suspect the pictures in the post you are talking about bit the dust along with the other attachments in the other threads during the time Richard had problems with the forum :(
Edited to add: my mistake, the dead picture links are due to the loss of an external website :( As Richard explains below...

So unless someone downloaded them, or they got archived, they are lost :(.

I wonder how the speaker is fixed inside the box ?
No screws ?

Where you see no fixings, it normally glued into place.

Not my fault - the images were hosted on another site which is no longer running:
