A Tube Dj Mixer Build

[joshco]

Hi,
Here is a 4+2 Stereo Channel Mixer I have built. The two Phono Channels are switchable to Line level.
Inside the unit are some Urei1602 Phono Preamps, Studer 169 EQ's, some basic Opamp Modules for Cue Mixing and a Tube Output Stage, as well as a three band Isolator on the Output Bus.
All in all it sounds pretty sweet, and the Tube amp has a very colorful sound, since it ran from technical point of view beside the bias point. Its a 12AX7 on 90Volts which can nicely driven into some typical distortion, which makes it perfect for digital sources.

Best Regards
T.

and another one.

Panel work was done on a diy'd cnc.

On top is three band Isolator, for more musical expressions, similar to the Bozak but based on opamp filters.

Thank you!
I have no inside pictures, since it has very much cables inside. The next time the pots will be pcb mounted. On this one the stereo channels and mixing boards are sandwiched together.
