Bring the ultimate hybrid of British punch and tube warmth into your lunchbox. Hand-built in Chile, the Stam Audio 1073-5T—affectionately known in the studio world as the "Turbo Neve"—is a brilliantly unique take on the most famous preamp circuit in recording history.

This 500-series module gives you the massive low-end and midrange clarity of a classic solid-state 1073 front-end, but swaps the traditional output stage for an ECC83 tube and a custom US-made 5:1 steel output transformer. The result? You get up to 75dB of gain that stays crystal clear at lower settings, but saturates with incredibly pleasing, harmonic tube distortion when you push the input and dial back the output trim. It is an absolute monster on vocals, snare, and bass DI.

Why This Preamp Stands Out: Stam Audio is famous for their no-compromise approach to components, and the 1073-5T is no exception. It utilizes a UK-made Carnhill input transformer and a classic 1073 dual-input stage with two BA284 cards. To ensure the authentic vintage timbre, Stam populates the board with premium Vishay, Polystyrene, and Tantalum capacitors. Paired with vintage-style condensers or ribbons, it delivers a larger-than-life sound with stunning depth.

Key Features:

• The "Turbo" Circuit: Classic 1073 solid-state input stage paired with an all-tube (ECC83) output stage for the perfect blend of punch and harmonic richness.
• Premium Iron: Features a UK-made Carnhill input transformer and a custom US-made steel output transformer.
• Massive Gain: Up to 75dB of gain, making it perfectly suited for gain-hungry ribbon and dynamic microphones.
• Variable Impedance: Switchable between 300 and 1200 ohms to perfectly match (or creatively mismatch) your favorite vintage-style microphones.
• Built-in DI: Front-panel DI input for running bass, guitar, or synths directly through the 1073/tube circuit.
• Total Control: Stepped input gain, smooth output trim control, 48V phantom power, and a polarity reverse switch.

Technical Specs:

• Format: Standard 500 Series (occupies 1 slot)
• Gain: 75dB
