Telefunken W689 Rebuild Process

We’ve begun work on our Telefunken W689 M/S module with a thorough cleaning using good old elbow grease and our ultrasonic cleaning machine using a special non-harmful cleaning solution.  Everything is back together now and working.  This this is built like an absolute tank!   Our next step will be to integrate it into one of our boutique quality oak lunch boxes.  Check out the data from our testing of this unit with our Audio Precision APx 525 below.  Stay tuned!
