Please Jeff can you check if it is the right orientation for the thermal sensors?

No, according to TC74AO pdf data, this will be the right way.

And then, when you are in the focus of stereo-base - that's where the magic starts 😉 Phase accuracy plays its role at its best.
Hi Thimios,
Your version of the temp sensor is a bit different from the one I used, but as far as I remember, in all the versions the sensor part is placed under the board, so that the screw goes through both of them (a plastic spacer is used in between).
See the fragment of my build.
Cheers,
Valery

Thanks Valery.
As the number 1 pin is N.C according to TC74AO pdf,and pad N1 on the pcb is N.C,i think that isn't other option. 😕

21" century protection.
Picture n1 serial scan.
n2 main software Leaded!
I have one question only now.
Led is on even when amplifier-protection is off.
Led is on but with a little higher luminosity when system is on, is it right?

Thanks Jeff, because the luminosity difference is very little, i think that the off must be lower. 🙂
Or is something to do with led that is used.

I've had some LEDs that are just too bright in standby mode too. Increase the resistance of R22 to make it dimmer.
I have done this(R22=6K8) but now there isn't any difference betwen off-on.
Vled(off=1.98v)
Vled(on=2.2v),no visible difference.
Something doesn't sound right there! What happens if you remove R22 completely? What do you have installed for R21?
J8 pin1 = GND
pin 2 = power on switch (ground to turn on)
pin 3 = GND
pin 4 = Audiolab remote trigger (ground to turn on)
pin 5 = 12V trigger + input
pin 6 = 12V trigger - input

R21=430R
I will try to remove R22.
May be the build in switch led have a resistor inside?
