We recently finished a restoration on another pair of Wurlitzer 106P pianos for Jeff Tweedy. Each one of the three so far is a near one of a kind with custom sustain installations and custom amplifiers. For an in depth look of our previous restoration check out the first 106P tube “high gain” 106P here.
In this second round of restoration we dialed back the high gain 12ax7 preamp design in favor of a lower gain 12au7. This allowed for a more balanced output at all volume levels and we were very pleased. The power amplifier is still the same push-pull 6V6 design with bias based tube tremolo. We restored the third with a Warneck Research EP200 amplifier which is solid state amplifier designed by Tim Warneck at Retro Linear. His amplifier provides amazing tone with an incredibly low noise floor and a deep variable tremolo unit. –Have a listen to both as you check out the pictures below!
