The Locomotive Audio 86B-2 Vacuum Tube Preamp is an American-Style Stereo Tube Preamp Designed for Versatility. From beautiful glowing vocals, natural acoustics and punchy drums to overdriven and saturated classic tube warmth, the Locomotive Audio 86B-2 preamplifier offers a huge sonic palette for engineers and producers to explore. Rooted in 1950s American-style tube circuitry, the 86B-2 has a huge harmonic footprint and will remedy what you’re missing from a lifeless modern signal chain.
Missing some flavor?
Want more color options from one box? Tired of switching between preamps? Maybe you’re low on rack space or just starting your first collection of outboard gear and need some versatility. You might just need the kind of versatility that offers recording with mics, then sending recorded audio back through tubes and transformers in ‘Line’ mode for more coloration.
Tubes, Transformers and an Amplifier Design You Will Love
The Locomotive Audio 86B-2 is designed to get any amount of tube coloration into your audio easily. Its two-knob system allows the engineer to fine-tune the type of character needed. You can drive the 86B-2 and control the amount of tonal coloration in your audio. Save time with one preamp that can achieve a variety of sounds. Rounded out with features like a 20dB pad, 100Hz high pass, two mic input impedances, line level mode and high impedance front panel DI on each channel, the Locomotive Audio 86B-2 won’t sit idle in your valuable rack space!
Locomotive Audio 86B-2 Lineage
Introduced in 2014 as a modernized version of the Ampex 601 “suitcase tape recorder,” the Locomotive 286A (Locomotive Audio 86B-2 predecessor) showcased several of the best attributes from the 601. A pentode EF86 and dual triode 12AY7 were a crucial part of the sound worth keeping. The 601 could sound so smooth, but also be pushed into full distortion due to its wild amount of gain. This was a great way to get a large amount of use out of one piece of gear. On the contrary, the 601 was never designed to be used with high-output mics, so it lacked input headroom and needed input padding much of the time.
Taking this into account, we designed the Locomotive 286A by using the Ampex 601 circuit and modified it for modern use. We also added all the important mic preamp features like phantom power, pad, polarity, low cut and DI.
Now, the all-new Locomotive Audio 86B-2 updates the 286A with a new front panel, new circuit layout, separate mic and line XLR inputs, as well as a much higher DI input impedance. And best yet, a much lower price tag!
Unlock Your Creativity
Finding the right piece of gear to give your sound that “special something” might be one of the hardest parts of engineering. In our opinion, having an exciting combination of tools at your fingertips is the best way to get your creative juices flowing. The 86B-2 will help to unlock your audio engineering mind and allow you to focus on creating truly impressive audio.
