Dynavox TPR-1 Tube Preamp, as good as new ! Modified by The Audio Clinic Mr. Rody Mulder from The Audio Clinic made a better version of the famous Dynavox TPR-1 Tube Preamp. The schedule was modified and the sound was improved to a very lifely sounding but also very quiet preamp by the use of better components. Used components : - Ultra Caps capacitors - Clarity Caps - TKD Potentiometer - NOS Raytheon valves I bought the preamp second hand “as good as new” in 2016 but I never used it, I only listened to it when I receved it and afterwards it landed on a shelf (covered against dust offcourse). It was meant to be used with two small Tube monoblocks on my two Linn Kan model 1 speakers but it never got to it. In the meantime I started playing full active with a preamp with more connections (balanced and unbalanced) so in the end I’ve decided to sell the TPR-1. Just look at the pictures, the item is really as new !!
