Clock Pulse Generator

For many years the author has been approached by people who have managed to lay hands on an ‘antique’ electric clock and need an alternating polarity pulse driver. This is immediately followed by the question whether an affordable circuit for this is available. The design described here has been working very nicely for years in three of the author’s clocks. To keep the circuit simple and thus inexpensive, the author dispensed with automatic adjustment for summer and winter time.
