-------------------------------------------------------------------------------------------------------------------- April 20, 1978 HP-1175 Bulletin No: AC Power Supply HP-1175-1 Use of the HP-1175 and the HW-202/HW-2036 and HA-202 Combination A number of HP-1175 Power Supplies have been shipped with connectors that are not compatible with the above combination. To power the combination from the HP-1175, do the following: Remove the present connector [if any] from the gray cable on the HP-1175. Strip the wires and connect a female connector [PN 432-73] to each of the two wires. The wires will be a tight fit into these connectors. Then pust these connectors into connector housing [PN 432-723]; This connector will mate to the existing female connector on the HA-202. Connect spade lugs [PN 259-22] to one end of the DC (mobile) cable furnished with the HW-202 or HW-2036. The other end should already have the male connector housing which connects to the transceiver. Now connect the transceiver power cable (spade lug end) to the connector block on the HA-202 along with the power cable for the HA-202. Be sure to observe polarity markings. The transceiver and amplifier can now be powered together from the HP-1175 power supply. This combination will not exceed the current capability of the HP-1175. Future production will incorporate this connector scheme. ----------------------------------------------------------------------------------------------------------------- That's all that is listed for the HP-XXXX series (1966-89).
