Recreating the world’s most desirable mic preamp

With several other brands attempting to clone this vintage design, we decided to go the extra mile. We pride ourselves in delivering the most authentic replica.  Numerous endeavors have been made to achieve the original character, making us confident in saying that you will not find this level of component quality and craftsmanship in any other offering in this price range. When it comes to components, almost correct or similar will not do. We use the right components, and the result is the right sound.

 

A Sowter output transformer exclusive to Stam Audio

The first step was to obtain a replica of the original Marinair LO1166 output transformer found on the original units. In a joint effort with Brian Sowter from Sowter transformers in the UK, the Sowter B1540 was born, an exact replica respecting the original laminations, ratio and frequency response of the Marinair, exclusive to Stam Audio.

Warm sound and character

Lastly, there are the small details which make the largest contribution to the finished sound. We made the extra effort to source critical components, such as the Vishay and IC capacitors, 1% metal film resistors and most importantly a Toshiba 2N3055 output transistor, which all hugely contribute to the unit’s sound and character.

The Stam Audio 1073EQ features:

  • high pass filter
  • switchable low shelf
  • switchable mid band
  • fixed high frequency band
  • DI for bass, synth, guitar, etc.
  • polarity switch
  • 48V phantom power
  • impedance switch

Due to the unique coloration of this unit, your recordings will benefit from the recognisable warmth of the original, which is described by many as deep and incredibly detailed. There is a reason these units have been the most popular choice in studios for the past 50 years. They create the sonic footprint we associate with professional recordings.

 

The 1073EQ is made with better components

Unlike other offerings on the market this replica respects the original circuit and components. The differences, in order of importance are listed below:

  1. A Carnhill line input transformer.
  2. A proper Marinair LO1166 output transformer replica custom made for us by Sowter transformers in the UK.
  3. A 2N3055 output transistor
  4. 1% metal film resistors
  5. transistors (not BC550)
  6. Vishay and IC capacitors as per the original (not Chinese capacitors)

The Stam Audio 1073EQ will be completely hand made in Chile. This is the only way we can manufacture them with these types of essential components.

    This is a thing of beauty. Fantastic on my vocal chain. The pre amp is incredible on its own and the eq is bang on. Used this on the bass the other day and it really smashes life. I had some neve pre amps that I use also and it’s really hard to tell the difference. This is a no brainer!

  2. tim

    Worth the wait!! The Stam 1073EQ does not disappoint. Great vintage tone. As good as the originals. Some other clones kinda “get close” but this delivers the magic. Keep up the great work Stam!

  3. Daniel

    The vintage Neve tone you are looking for, plus an excellent EQ to add presence to your material.

  4. derekreesemusic

    WOW This is the Best preamp and EQ I’ve ever used,
    Without the eq the preamp has an awesome forward presence, with the EQ engaged it has a beautifully rich low end with a top end that is crisp and airy, thank you Stam Audio.

  5. Gavin

    Pre amp and EQ both sound top drawer, love mine

  6. RyanRuin

    The 1073 Pre/EQ has such a beautiful sound and is very versatile. First, all on sources, as an EQ insert, it completely blew away every 1073 plugin I own (UAD, Waves, etc). On live tracked vocals the sound was huge. I can only describe it as lush, wide and open with a rich tone. It put a smile on my face the second I heard with without even having to turn any knobs. When you start getting into pushing the unit harder, the distortions produced are very pleasant. I highly recommend this unit to anyone serious about recording acoustic instruments especially vocals. I also love 1073 on kick/snare, but it will sound good on anything. Extra brownie points to Stam for shipping it so fast as well (it arrived at my place in 4 days once it was shipped from their warehouse).

  7. Lutz Munka

    I do not have any experience with the original hardware, but the sound of this pre-amp is absolutely amazing. As soon as stam is selling them again, i ll order a second one! <3

  8. Pablo

    Fantástico preamp! Nada como enchufar el micrófono y tus voces encajarán perfectamente en la mezcla.
    Probado también en un bajo y el low end es impresionante!
    Felicidades a todo el equipo de stam audio por la fabricación de uno de los mejores aparatos que he tenido ocasión de probar.
    Genial servicio al cliente y rápido envío!

  9. Dave

    I’ve got 4 of these and I’ll probably be ordering more. These sound great and all of the input and output options on the back make my work flow so much easier. I’ve been happy with everything I’ve bought from Stam so far and they’ve really outdone themselves with this one. Thanks Stam!!!

  10. Jamie Sitar

    I bought a pair of these with the line input transformer and the Sowter output. They’re incredible. They sound just as huge and smooth as the originals, but they’re dependable and affordable. So far, I’ve used them on vocals, acoustic guitar, piano, and synth – all with the expected stunning result.

  11. Stephen Gallagher

    My 1073eq took almost 2 years to arrive …was it worth the wait? YES! ABSOLUTELY! This unit sounds beautiful. I am a very happy man. Thanks Stam!

  12. Al Isler

    I waited patiently for the model with the Sowter transformers and it was totally worth it. This thing sounds absolutely gorgeous. Like velvet butter. It’s also whisper quiet. I engaged the DI and cranked the gain to max and no noise at all.
    The sound is huge, smooth, but still incredibly detailed. It made my “whatever” guitar in my “whatever” room sound (almost) like a Fleetwood Mac record. I’m incredibly impressed and totally in love with it. Can’t wait for the rest of the stuff I have on order 🙂

  13. Karnig Baghdassarian

    This is a honestly huge sounding pre amp!! It makes the singer smile. it has a certain touch of magic. Vocals seriously become huge, and believe me i tried a range of valuable pre amps. it has the dark vintage tone. it does have a certain tone. and it has HUGE amount of gain!!!! Talking about the EQ, the eq is sooooooo smoooth, u raise the high end to the end, still do not get any spitty type of effect. its so silky. the low is not muddy AT ALL!!! amazing piece of gear.

  14. Daniel Salvador

    Excellent preamp and EQ!! I’ve always wanted a 1073pre+eq and I could never afford it, but thanks to Stam now I was able to afford one and get an amazing piece of gear for a fraction of the cost of what the real thing would’ve been.
    In terms of quality, it is excellent too! Couldn’t have a better preamp at this price and at this level of quality, thank you Stam! 🙂

    My first experience with Stam and I have to say it has been excellent. I bought a pair of these with the line input transformer and the Sowter output. Pre amp is huge and the EQ is super smooth. Everything it touches turns into something special . Service from Stam has been great from Order to Delivery. Already got my eye on some more Stam products
