Finished. Gain is quite low, picking up a little bit of hum at high levels on the pot but then it is currently sitting close to the extension lead.
Sounding pretty good so far.

I’d look to wire routing for the hum.
Possibly route the two signal wires behind the heatsink… or…
In an ideal world I’d flip the amp boards/heat sink thru 180.
Try grounding the internal signal stuff at one end only.
If you’re commoning circuit ground to mains Earth, connect to Earth via ~50R + 100n paralleled.
A grounded band around the tranny can help with stray fields sometimes.
Quite a lot of wiring could be way shorter to good effect, and twist complimentary pairs together.

Yep, quite possibly. This was a first lashup, so improvements could occur if botheredness is in evidence.
The hum there is is directly connected to the volume, so it is upstream of the pot rather than anything else.
Best way to advance your learning is making a few minor mistakes and fixing 'em - I do very little else TBH…

thanks paul ,
New OB panels built as a test for a mate in the village (he was v impressed with OB’s a while back)
I should find out this week if the Sonos Amp he has is a sonic match so he can build his own. With the Decware DIY kit kindly on loan from Graeme plus a Behringer Inuke I reckon it deffo is a goer.

Hey Andy, I see vinyl in the pic, I thought you had sold it all, or is that the start of a new collection?
