TK Audio DP1mk3 Dual Preamplifier  From TK Audio

The midrange crunch of the germanium sound of the mid 60's, the low mid punch and thick sound associated with British class-A from the early 70's and the modern tone from the 80's and 90's; all in the same box.

TK Audio

Manufacturer's Description from TK Audio

The DP1mk3 is a dual channel preamp based on a unique hybrid design including both vintage and modern circuits. Germanium and silicon transistors, along with integrated circuits, make the sound character expand over several decades. The midrange crunch of the germanium sound of the mid 60's, the low mid punch and thick sound associated with British class-A from the early 70's and the modern tone from the 80's and 90's; all in the same box.

The input-stage is built around a high quality Swedish Lundahl transformer. The preamp section is followed by a germanium unity-gain stage for coloration. Finally the DP1mk3 has two different output stages, an electronically balanced output stage or a discrete transformer-balanced class-A stage, built around a heavy Carnhill output transformer. The vintage class-A mode produces a fat and punchy sound with mid range character and a warm top-end; the germanium mode adds even more harmonics to the sound. The IC-based output stage is less colored and perfect for clean amplification. 

With up to 80 dB gain the DP-1 can handle quiet sound sources like ribbon microphones. High impedance inputs are positioned on the front for easy access when connecting guitar, bass or synthesizers. It's also possible to crank up the input gain really loud and run a hot signal through the preamp to make it distort, and then use the output volume control to lower the output gain. DP1mk3 offers a unique set of flavors at a very sensible price.

The new updated version is now provided with a HP filter, 80Hz/12dB.

About Manufacturer

TK Audio is based in Halmstad, a small town in the southwest of Sweden. It started out in 2008 as an additional brand to Vintagedesign as we wanted to develop products with a bit more modern style. Thomas Kristiansson (or TK as his friends call him) is the mastermind behind both Vintagedesign and TK Audio and he has been working with electronics, cords and sounds in different kinds of professions his entire career.
Our philosophy is to produce creative audio solutions and assemble them in Sweden.
We buy the chassis from a local manufacturer and the main part of the panels is also produced nearby. Up until just recently we have assembled and soldered the circuit boards by ourselves but as the demand for our products has increased we can´t keep up so now we also use another company to help us out. They are situated just a 2 hour drive from Halmstad so we can still proudly say that our products are hand made in Sweden. We take responsibility for keeping our production as environmental friendly as possible and by having full control over the production and of course making all the final assembling by ourselves we can make sure that the quality always is top notch!
