Holiday 7125 Integrated amplifier

This integrated amplifier is made quite simple but I like it's overall sound. It driven by 4 2SD234 transistors on the output with an input voltage of about 24Volts on each of them. Before I remake it's main board, it sounded very bad. Lot's of distortion in the sound caused by old capacitors but too, out of tolerance resistors and bad bias adjustment. It was a totally different amplifier after the work. Below main board, it's identified as "Sound NS-119E". If "Sound" is the brand maker of the board, Sony could be related with this design. Main outputs are from Toshiba though.
My rough estimated would be around 10 watts per channel. It have generous bass/treble controls.  2 unusual features with this one are the 2 alternate phono PU selector options (MM and Xtal) and the integrated microphone mixing.
