Fixing 1983 Soviet VFD clock Elektronika (unedited)

Today, let's repair a broken Soviet Elektronika 2 (Электроника 2) digital alarm clock with a VFD display made in 1983. Unedited video recorded using just the pause function of my phone. In those clocks, the electrolytic capacitors often fail open circuit, resulting in buzzing noise and flickering display. The VFD display may wear out over time or get damaged by dropping the clock. Also the Soviet 32 768 Hz crystals often fail or get very inaccurate. Occasionally the soviet chips K176IE18 (К176ИЕ18), K176IE13 (К176ИЕ13) or K176ID3 (К176ИД3) fail or the display develops internal short circuits. The display is IVL1-7/5 (ИВЛ1-7/5) and it can be replaced by a similar ILC4-5/7L (ИЛЦ4-5/7Л). I also tend to adjust the 5V~ heater voltage using a series resistor if it's higher than it should be.
