Sabaj A1 2022 stereo integrated amplifier measurements

Some internals. Cheap chinese design and low end parts.
Bluetooth IC is probably JL AC6903B - just SBC codec,
SGMicro SGM3710 as audio switch (BT/RCA)
Couple of STM TL072C opamps
Pair of DC/DC MC34063 regulators
older Eximo Merus (Infineon) MA12070 amplifier
