Berliner Dual Pentode Preamplifier


Berliner, a 2 channel mic/instrument/line tube preamp, is our take on the legendary Telefunken V76, but with some important twists that set it apart from the 50’s original.

Staying true to our “No Cloning” concept, we take the venerable V76 to the next level! Keeping only what is needed to achieve that “to kill for” tone and taking inconsistency, unreliability and one-trick-pony-ness out of the equation!

The front end is a dual pentode variable gain stage with a regulated bias and EF86/EF806 tubes (instead of the discontinued EF804). This stage behaves and sounds exactly like the original.

The output though, is a hybrid circuit borrowed from the Creamer. Without the step-down transformer, it preserves the sweetness and definition of the first stage and offers both transformer coupled and transformerless (switchable) output. We also added instrument (DI) inputs on the front panel and dedicated line input transformers so that this baby can be used to warm up your mixes as well.

The amount of detail Berliner reveals is staggering! And all with that sweet tubey character! It will meet or exceed the expectations of an engineer hunting for the best V76 unit on the used market and add new features that classical tube preamps could’t even dream about.

Serbian megastar Željko Joksimovic recorded his “Milimetar” hit vocal using a Microtech Gefell large diaphragm condenser mic plugged into a Berliner. You can even see our Creamer Plus and Berliner preamps in his studio rack several times during the video:

Here’s Berliner on male vocals using an Advanced Audio CM47. A very flat, smooth mic with no presence hump. Acoustic guitars were recorded through a Silk Road.
