The Pultec program EQ in a space-saving 2U rack – same parts, same specs as the EQP-1A. The Pultec EQP-1A3 is the 2U (3.5-inch) version of the 3U EQP-1A, introduced in 1971 when the controls were rearranged to save rack space – “same parts, same specs”. It was the first unit Pulse Techniques brought back into production; New York’s Power Station once had 24 in each control room.
