The cross is the place where you can insert a jumper to disable the denoiser, for test or trouble-shooting for example. It is not compulsory of course.Hello Elvee
greetings and thank you for posting the schematic
C3 220uf is it used there is a cross on it
The ZTX is the absolute best, but others come close. You can use a BC337 for example.warm regards

ztx 851 any substitute in schematic enclosed
You can connect the output capacitor of a die/denoiser to the base of the transistor. The 2.2µF needs to be removed, and the value of the 220µF can be vastly reduced, according to the values of the voltage divider.Hi guys,
i have this circuit for my COD dac of twisted pear audio, one for analog and one for digital section set to 7.5Vdc. i want to replace this one and i would like to know which one do you suggest?
thank you! Maxpou

You can insert a 470 ohm resistor between the base of the darlington and the diode string, and lift the 220µ from the gnd to use it as coupling cap for a die/dienoiser, but the benefit regarding noise will be small, because it is already quite low.for this schematic
