I made the amplifier’s power supply turn off when USB’s power supply is turned off by TU-8100.

TU-8100 can be built into the PS-3249, and you can build it in according to the manual.
Here I made another attempt to devise a remodeling. Even if I turn off a PC, turning off the interconnecting equipment tends to be forgotten.

The same is true for an amplifier.

If I forget to turn off the H80, it is a hybrid configuration and electricity consumption is low, so it is within my tolerance level. However, when I forget to turn off the single-ended Class-A vacuum tube amplifier in “energy-saving summer”; I have a crippling sense of guilt.

The USB’s power supply will turn off if I shut down or hibernate the notebook PC, so I took advantage of this, I detected USB-DAC’s bus power was turned off and remodeled it to shut down TU-8100 as well. (Basically I cannot turn off the bus power even though I shut down the desk top PC. However it is possible to use it if you can change the setting to turn off.)

The remodeling itself is simple if I completely synchronize with the USB. However if I do so, I have to connect to the PC in order to turn on the amplifier even when I want to listen to a source other than USB-DAC.

Therefore although the number of parts has increased slightly, when the bus power goes from ON to OFF, the amplifier also go to OFF, but I made when I turn on the amplifier again I can turn it on without connecting to the PC.

(The amplifier doesn't start automatically in bus power OFF→ON. )
I add a circuit to TU-8100. This is the image of the figure which I wrote in an additional circuit to the TU-8100’s instruction and I mounted on the back of the circuit board.
