The Stam MEQP-1A+ is unlike any other Pultec EQP-1A replica, combining three units into one. It features the mid-band section of the Pultec MEQ-5, the solid-state 2520 op-amp output stage found in the EQP-1ASS, and the original EQP-1A, all selectable with the flip of a switch.
This design not only makes the Stam MEQP-1A+ the most versatile Pultec replica available but also one of the most faithful-sounding recreations of the original. Additionally, Stam Audio introduced the ability to boost the mid-band, an innovative feature that expands on the original’s capabilities.
After retiring the MK1 EQP-1A in 2019, years were spent developing custom-made input, inter-stage, and output transformers, along with accurate inductors, to revive the authentic sound of a vintage Pultec. The Stam MEQP-1A+ is built using three Sowter Audio transformers made in the UK, a US-made 2503-style custom output transformer, two Stam Audio SA-2520 discrete op-amps, three Carnhill inductors, and three tubes, including the 6X4 tube on the power supply, renowned for its signature “sag.”
Sowter transformers, although costly, were chosen for their superior low-end performance, sonic timbre, and unique frequency response, faithfully reproducing the tone of vintage units. These components, combined with the SA-2520 op-amps and Carnhill inductors, ensure the Stam MEQP-1A+ offers unmatched tonal authenticity and sonic precision.
The Stam MEQP-1A+ is crafted with premium components, including custom Sowter transformers, Carnhill inductors, NOS tubes, Corner Dubillier capacitors, and Ohmite carbon resistors. Every unit is hand-assembled by skilled engineers in Chile with meticulous attention to detail.
After assembly, each unit undergoes a rigorous 72-hour burn-in process, ensuring flawless performance and reliability for years to come. This commitment to quality makes the Stam MEQP-1A+ a tribute to the legendary Pultec while offering innovative features for modern studio workflows.
