Discrete dual channel 1073 preamplifier
The 1073MP is the most authentic and accurate sounding replica of a vintage 1073 preamplifier available today.
Unlike most 1073 clones and current made “N” 1073’s the 1073MP uses a custom british made Sowter 1777 output transformer which is the only transformer we have found to truly replicate the original Marinair LO1166 smooth top end and larger than life low end which made this circuit designed by Rupert Neve 50 years ago the most sought after preamp in the world. With it’s stunning Marinair transformers, simple yet beautiful circuit, hand selected transistor as well as tantalum and polsytrene capacitors this preamplifier is by far the most requested tool around the globe.
At Stam Audio we have been building 1073’s replicas for almost a decade and decided to do our final revision with a custom Sowter output transformer, Carnhill VTB9045 input and vtb9046 line input transformer, tantalum, polystyrene and Vishay capacitors as well as BC550C and 2n3055 transistors which are all measured one by one before being soldered into each channel. While time consuming this is the only way to achieve the same frequency response, THD and timbre found on vintage units. Without cutting any corners and making sure that it sounds exactly like an old unit from the 70’s we are confident that the 1073MP will be the last 1073 you’ll ever need.
The Transformers
Transformers are the single most important part of this circuit and the heart of any 1073 preamp. They provide the clarity and larger than life sound with unique low-mids and low end. The 1073mp uses a Carnhill VTB9045 input transformer on each channel which is a direct descendants of the the original Marinair and a custom UK-made Sowter 1777 output transformer which perfectly recreates the original Marinair LO1166 output transformer like you have never heard before. All transformers are tested and shipped from the UK to our lab were we tested them one by one to ensure each 1073mp is in spec and sounds the same
Capacitors and Transistors
After the Iron the one thing that makes this circuit stand out and gives it it’s original character are the polystyrene, tantalum and Vishay capacitors as well as the BC550 and 2n3055 transistors. Every single part is auditioned, measured and carefully hand soldered into each 1073MP. Precision metal film resistor are used through out the circuit with a 21 position gain switch providing up to 70dB of gain
Hand made
Each 1073MP is hand made in our lab in Chile and comes with a 2 year warranty.

The 1073 MPA is a gorgeous sounding unit. It has a very smooth sound with the smiley face tone that we have all come to know and love. Comparing to UAD 1073 plugins and some other cloned preamps I own, the 1073MPA has a more rich and beautiful 3d image, and sounded like a record from the start. The plugins fell short and sounded dull, 2d, and flat. Depending on the mic choice and how you mic your source, you probably won’t even need EQ if you go through one of these units. Highly recommended.

Don’t think twice and get it! This thing sounds absolutely amazing.
Very lucky to own 2 of theses units.
Dave Cox –
Very nicely built and sounds great. Fantastic for low output mics like the SM7b and compliments my vintage ribbon mics well. I’m very happy with the 1073MPA and will be buying another in the near future.

Happy owner of a 1073 MPA (with sowter mod). This is a fairly new acquisition for me but I’ve really put it through it’s paces the last couple months on a film project and I am supremely impressed. The clarity, presence, fullness of the sound is truly remarkable, especially at this price point. My synths, vocals, rhodes, and guitars all have that little something extra. While I don’t have much familiarity with the OG 1073’s, I have spent a lot of time with a pair of pristine 1084’s and to my ears, Stam’s recreation of that preamp is absolutely spot-on. Bravo and thank you!
Warren Hunter –
Everything you expect it to be. Loud and lovely rich velvety saturation. Built like a tank and the DI is also surprisingly better than I expected. A no brainer at this price point. I primarily use this in my portable rack setup for out of studio vocal work but would happily use it in a normal studio environment.
Robert Moyle –
I waited a long time to receive this baby, but it is the best sounding version of this preamp we have in our studio and we have 2 other more expensive brands. It’s bigger and richer sounding. I love it. Thanks Stam. They kept me going through the wait.

I love this pre-amp. I use it on just about everything. I noticed that if I turned it up to very high gain and don’t trim it down, it began to oscillate and make wild sounds. Although these came into use once, I reached out to the Stam team. They sent replacement parts, gave instructions for my tech, and covered my repair costs. That’s the only reason I put 4 stars. But honestly, 5 star pre-amp especially for the price.
Nathan Boots –
i have two sets of this pre. one with sowter, one without. both sound just great. Electric guitars, bass, overheads and rooms have never sounded better. i’ve tried GAP, Warm, GR, and this by far stomps them.SO happy i waited for them.
Guy Cooper –
These sound great, I’ve got a couple with the Carnhill and a couple with the Sowter options. They are raw and a great addition to the studio sounds great on drums, guitar and vocals and really bring out the texture of the parts through the mics. They are well built and solid to touch, ordering and delivery was easy and they came to Australia well packaged. Highly recommend for some 1073 sounding pre’s at an amazing price.

I bought my first Stam Audio 1073 MPA around Christmas 2018. I have used it non stop. It is super reliable & sounds amazing. I have used the real thing many times and this is super close to that. In fact for the money, you can’t beat it. It is built like a tank with top notch components. And it’s actually more reliable than a vintage neve. I will keep buying from Josh at Stam with confidence. They offer so many cool versions of vintage gear. You really can’t beat them. And the customer service is great. They will help you with any concerns. Only down side is since the company is growing and everything is hand built, it can take time. It’s not a crazy wait time but in my opinion the wait that you may encounter time to time is worth it. Seriously can’t say enough great things about them.

We have been using our Stam Audio 1073DPA For about a year now and we are extremely happy with the results. It is as clear, full-bodied and trouble-free as we could have hoped for. We rely on it every day and it is a workhorse preamp! Vocals sound clear and full. It has never given us any problems, and we want more of them! We know we can rely on Stam to deliver something special and useable; there is nothing in this price range we can think of that gives us a better sound quality. It has helped us take our music to the next level of quality for a very reasonable cost.
Features we love: the insert point (used this for sending vocals through guitar pedals and tape delays), well-built, Sowter transformers.
There is music in this box.

I use my 1073mpa on absolutely everything. And it all sounds good. Especially on electric guitars, vocals, and bass. Keys, percussion….everything. The saturation is glorious and it is THAT sound. Great price, great build, great preamp. I will keep on buying from Stam.
borhythm –
Finally received the 1073MPA w/ sowter transformers, it was well worth the waiting time. So far I used it for acoustic guitar, drum overheads, vocals. Beautiful round tone, every signal that goes through it becomes much more easy to mix. I cannot compare to an original 1073 but I’m very happy to own this preamp and will definitely consider buying another!
Raúl –
Everything sounds big through this preamp. It has a great warm saturation and you can really feel and hear the quality of construction. I use it on recordings and also in the mixing process re-amping old tracks to get a new/different flavour into my mixes. It was worth the wait and I would totally recommend it.
Boris Gonzalez –
It is the best preamp I’ve used, built as a tank to last a lifetime. Joshua, Camila and the attention of the whole team is really good. They answered all my questions, I totally recommend this preamp, I will definitely continue shopping at Stam, I want all the microphones!
Wolfgang Hendrich –
This is a wonderful piece of gear that performs everything I expect from a unique preamp. Carnhill and Sowter Transformers are top notch and the possibility to side chain additional equipment is absolutely useful. Thank you so much Stam Audio for this superb gem!

Fue el primer producto que compre a Stam Audio, tomo su tiempo en llegar, pero cuando lo hizo quede sumamente sorprendido, me dio exactamente lo que necesitaba y daban ganas de pasar cualquier pista por el para ver que sucedía y como esta de alguna manera mejoraba su calidad considerablemente, es una maquina sumamente solidad y se nota que su construcción interior es de alta calidad y excelente manufactura.
Jamás parare de comprar hardware a Stam Audio demoren lo que demoren es una buena inversión y lo que llega es 100% pura calidad y sabor.

Potential customer here, intrigued by your products, I went fishing & found some pictures & video’s on youtube, your facebook page of your workshop & people who work with you. May I suggest making your website more personable & include some of the behind the scenes work & the people involved etc. This will add confidence in buying your products, priced well as they are people also need to know what you have in stock & the wait times involved when placing a deposit. Cover these bases & grow your business with confidence from both sides of the equation my friend.

I went from vintage V76’s to Vintech 1272’s, to Aurora Audio GTQ2, to UAD unisons. I will never use a software mic preamp emulator again.I don’t do this for a hobby, So-I went to test out the 1073 mpa with a Shure 57-I didn’t feel like rigging up my KILLER STAM SA-47 mk2 for a preamp test. I sang a little (I have a kind of gravelly Greg Allman voice) I was like “Are you f#%*ing kidding me?!? This sounds like a high end tube mic!” It’s Josh with his sonic wizardry. A 57! I won’t even use a 57 on my guitar cab…(Ribbons) For me, this is THE 1073 to have.
Matt Corsi –
This has become my favorite mic pre! Took delivery several months ago and have been comparing to a number of “classic” mic pres and this keeps beating everything I put up against it. Love it on female vocals, acoustic guitar, clean electric guitar, snare, room mics, drum overheads. Works well with large diaphragm tube mics, SDC’s, dynamics, anything I throw at this amazing piece of gear just sounds good.
Justin –
My first mic pre, lost my analog virginity with this unit. I’ve been around a bit now with a lot of other nice preamps, and “the Stam” as it gets called here, never disappoints. Love it with rode NTR ribbons in a nice room on piano, love with room mics for drums, love it for everything.
RENATO MOREIRA –
1073 do Stam sem duvidas tem uma saturação divina perfeito para minhas captações de voz, pratos de bateria e guitarras, adoro o grave do transformador Sowter.
Pete Lord (verified owner) –
Well I finally got one, I bought it slightly used on reverb. Let me say this, I’ve had the real thing as well as the BAE 1073. This sounds the best to me. This has a really nice 3d sound to it, very clean with nice warm lows, and soft highs. I’m very impressed with Stam’s quality, I’d recommend this all day long.
Chuck Schubert –
This preamp is a thing of beauty. So rich and
full sounding. I have paired a number of top shelf mics with this and they all sounded fantastic, but the Stam SA-47 Mk3 and this preamp is a match made in heaven! Josh is an audio genius!
Jake Macdonald –
We’ve had the mk1 in our studio since about 2019, and it is fantastic. Crunchy or clean, it lets you dial in just what you need. Great on vocals, guitars, and we really love it on snare mics.
