HP-23A



The HP-23 family of Power Supplies for the SB-series started with the HP-23 in 1963. It was replaced by the HP-23A in 1968, which in turn was replaced by the HP-23B in 1973, which in turn was replaced by the HP-23C in 1978 and was produced until 1979. The Hewlett Packard Company did not let the Heath Company use HP as a designation for their products so the HP-23C then became PS-23. It can either stand alone or be placed inside the SB-600 speaker box. Even if these power supplies originally were meant for the SB-series they also became the standard power supply for the HW-100/HW-101.
