*Instructions and wiring kit apply to console models (203, 206, 206A, 207, 207A, 210, 210A, 214, 214A
and 270) where the piano has been separated from the console (or, “chopped”) and if speakers are
present, they are model 200A type and have been installed in the lid. There are no provisions or
instructions for utilizing the console portions of these models.

VINTAGE VIBE –WURLY AMP –CONTROLS / FEATURES
1. Volume:
Your stock volume potentiometer will serve as the Master Volume control for both
the Speaker / Headphone Output and Aux Output.
2. Outer Tremolo Knob:
Controls the depth of the tremolo. When set fully counter clockwise the effect is
bypassed. The effect becomes deeper as the knob is turned clockwise.
3. Inner Tremolo Knob:
Controls the rate of the tremolo when in variable mode. When set fully counter
clockwise the effect will be at the lowest rate setting. When turned clockwise the
rate increases.

4. Stock / Variable Tremolo Switch:
The inner tremolo knob also serves as an On-On push-button switch. Pushing
the switch will toggle between variable rate mode and a fixed rate matching that
of the classic Wurlitzer models.
5. Speaker Cut:
This slide switch found on the amplifier PCB (S1) will effectively mute the
Speaker / Headphone output signal. This can be useful during some recording
and live performance situations.
* If no connection between speakers or a headphone jack are made to the
amplifier this switch should be set to the Off position.
6. Level Adjust Trim:
This trimmer, located on the amplifier PCB (VR3), sets the overall signal level
available at the Master Volume control. It should be adjusted so that, when the
Master Volume is set fully clockwise, playing at hardest dynamics does not
produce distortion from the speakers.

6
Vintage Vibe Rev: 1.0
Wurly Amp Manual MAY 2020
7. Aux Output Trim:
This trimmer, located on the amplifier PCB (VR4), sets the overall output level
available at the Aux Output jack prior to any Master Volume adjustment. Set
desired output level for interfacing to an amplifier, PA, DI, etc. This trimmer
should be adjusted only after having first set the Level Adjust Trim (VR3).
8. FX Loop (Optional):
The FX Loop allows the insertion of effects into the signal path within the
amplifier circuitry. The result is that the signals at the Aux Output and
Speaker/Headphone Output will both be affected accordingly.
The FX Loop jack is a 1/4" TRS normally closed insert jack. When no cable is
inserted the Send and Return are connected and signal passes through normally.
When a 1/4" TRS cable is inserted, this connection is broken and the signal flow
is as follows:
Tip = Send
Ring = Return
Shield = Ground
Utilizing either a Y/Insert Cable or appropriate breakout box, connect your
desired effects.
The FX loop is located prior to the tremolo circuitry.

VINTAGE VIBE WURLY AMP INSTALLATION INSTRUCTIONS
Models 200/200A and Chopped Consoles
1. Ensure that the piano is unplugged from the wall outlet and that all voltage has
been drained from the stock amplifier. Remove electronics rail from piano.
*For 200A pianos, save the screw that secured the AC inlet “earth ground” wire
to the rail as you will need to re-install this at the end of the installation.
2. Detach power transformer secondary wires (blue, red, red, red/yellow) from stock
amplifier PCB. If clipping, do so close to PCB.
*For 200A models, the green ground wire connecting the stock amplifier PCB to
the rail will not be utilized in the new installation.
3. Desolder wires from Volume Potentiometer lugs 1, 2 and 3.
BEFORE:
AFTER:
*If there is a jumper between the potentiometer shell and lug 1, remove it.

4. Remove Vibrato Potentiometer (200/200A) or Rotary Switch (Chopped Console)
from the control bracket.
5. - Desolder or clip the Orange wire at the Headphone Jack.

200A: Speaker Molex Connector
6. 200 Model Only:
- There will be two black wires soldered to one of the terminals on the Right
Speaker. Determine which wire’s other end terminates at the stock amplifier
PCB and desolder or clip it from the speaker terminal.
*There should still be an Orange Wire and a Black Wire connected between the
two speakers.
