Projects > Analog Allstars EQP-1S5 500-Series Pultec EQ
The EQP1S5 is a passive, solid-state EQ for the 500-series/51x Alliance based on a Pultec design. The EQP1S5 uses the frequency selections from Pultec’s special “S” series and replicates the discrete opamp output stage of the solid-state Pultecs. In order to hew as closely to the original design as possible, the it uses custom-wound molypermalloy, toroidal inductors as well as custom reproductions of the original HS56 transformer.
