Alfa Elektronika 12-41 (Alfa Электроника 12-41) alarm clock was produced in USSR during 1980's.
It was a predecessor of a newer version Alfa Elektronika 12-41A.
It was built with a flat 4-digit 7-segment VFD display IVL2-7/5 (ИВЛ2-7/5) 10mm high digits and a red 5mm LED diode to indicate enabled alarm.
At the front panel it has buttons to set hours and minutes, a switch to display in "minutes:seconds" mode, a switch to display alarm, and a reset button.
At the top there's a low/high brightness switch and alarm enable/disable switch.
It operates from 220V 50Hz mains. It draws about 1W. The original price was 18 Rubles.
My clock had a dried out electrolytic capacitor 20uF / 100V. After capacitor replacement, the clock works well.
