Nothing strange, for Europe they supply American plugs with European adapters.

Two more such devices need to be installed inside for the analog line power circuit.)))

No, I meant capacitors for power OPA1612.

Finneybear wrote it right. The type of capacitor is important because our power supply produces high-frequency noise, a capacitor with a low ESR is needed.

I can not find a 100uf 16v capacitor with a size of 3.2 mm.

How did you do linear power + -10v? Or did you connect an external power supply? Is it possible to show a photo?

777 said: I don't understand why you want ultra-low ESR in the signal path. For pass capacitors, a low ESR is not a priority. Much more important is its non-linearity at sound frequencies, which is higher in polymer tantalum capacitors. In this way, they contribute an equalizer effect.

Tell me please where did you buy Elna Silmic II?

And what if we install another operational amplifier? And summarize the signals after the op amp? To get rid of feed-through capacitors.О

Initially you wanted to install these capacitors https://www.arrow.com/en/products/t520a107m006ate045/kemet-corporation Why did you change the decision?

There are a lot of mistakes on your scheme. In the event of a fault, there was a constant current in the headphones of 10 V. Please simulate a short-circuit of the diode after correcting the circuit

Then it is better to use Cap Tant Polymer for example these https://www.arrow.com/en/products/tcjy157m016r0070/avx

Try to apply external power + -10v bypassing TPS54331.

Yes it is

Is the input ground disconnected from the output ground?

Can someone explain how in DX3Pro they get -10v?

Where can I buy this key?
