Good point.
In my build the tabs of the TDA2050's are insulated from the heatsinks.

Ty Olaf ,
It is not a kit
, i have built 10 of them.I have got 5 remainingDimension: 25mmX60mm
Later I´ll upload more photos with the other components of my micro system
.regards!
Depends on what you want the thermistor to do. If you want to use is as inrush current limiter, it goes in series with the transformer primary.
TPA6120
Just finished my headamp based on Texas Instruments TPA 6120. I'm quite happy with the design, the only thing I would suggest to the designer is to use 10M tantals in stabilizers ground path for better noise rejection and reverse diodes to protect the stabilizers. Since I didn't do any measuring, it is just my suggestion I don't know how much better the S/N would be. The sound is really nice, pure and clear.

An externally hosted image should be here but it was not working when we last tested it.

hi grakka,
if it was me, I would either twist the input wires more tightly or just use shielded wire. to and from the pot, too.
the pot also looks a wee bit close to the trafos. I'd worry a little about hum pickup and if you were able to push the pot to the other 'wall' (rear) it could only be better, still.

So my LM3875 Gainclone finally has a case...
It looks very 80's, but not really that out of place next to the Technics SL-10.
I will get something nicer later on down the track when I have time. Probably in another five years!

Are you sure those small heatsinks are sufficient for the ICs power dissipation? They are so small and might trigger the internal themal protection circuit a little too soon.
Here it is a video of my tda2050 amp working also there is our usb-mp3/wma/wav/vorbis player , it´s in developing yet.
In the video you see the volume potentiometer and 4 buttons , play,stop-removeusb- ,<-- , --> . Only works the stop button
