General Description:
The active element is the low-noise operational amplifier (OU) U2. The scheme is installed OU series TL072,
but it can be replaced by any similar, for example, NE5532, OPA2134, OPA2132, etc.
The circuit is powered by one or two batteries (or batteries) 6F22 “crown”. By using your own power, you can
increase the operating time of portable playback equipment.
At Shelter U1, a circuit for creating a virtual earth for converting a unipolar power supply into a bipolar power
needed for the operation of the amplifying chip U2 has been assembled.
It is possible to supply the circuit from a mains unipolar source for stationary use of the device [2].

2. The mains power supply must be linear and have a minimum ripple level so as not to create noise during
playback.
