Warneck Research Upgrades for Vintage Wurlitzer Pianos

Warneck Research Wurlitzer EP200 Amplifier Board

Recognizing that nothing really matches the classic sound of a Wurlitzer Model 200 electric piano, vintage keyboard and amplifier repair/restoration company Keyboard Cottage introduces two new upgrades for vintage Wurlitzer electric pianos.

The Warneck Research Wurlitzer EP200 replacement amplifier board (pictured) faithfully reproduces the sound and characteristics of the original Model 200 amplifiers—only without all the noise. Completely redesigned from the ground up, the new amp employs low-noise circuit and layout techniques. When coupled with reed bar shields (included) to minimize 60Hz hum, the performance outperforms fully restored 200A amplifiers.

“We were very fortunate to work with Ken Rich at Ken Rich Sound Services in Los Angeles to further optimize the EQ curve for the Wurlitzer EP200 Amplifier Board,” notes Keyboard Cottage president Tim Warneck. “Ken has been working on keyboards since the ’70s and is one of the music industry’s best-kept secrets. He has done full restorations and provides service for many major artists.”

The EP200 Amplifier Board features the EQ curve and sound shaping characteristics of a properly restored original 200 series amplifier; authentic vibrato; very low noise; an improved power amplifier; user-selectable variable or fixed line-out configuration; and a drop-in/solder-free installation. The EP200 Amplifier Board retails at $379. Production units begin shipping in June 2010.

Designed to work with the new Warneck Research Wurlitzer EP200 Amplifier Board or the stock Wurlitzer 200A amplifier, the Warneck Research VariVib Variable Speed Vibrato Upgrade reproduces the original style vibrato waveform and offers linear variable speed control (approximately 1 Hz to 15 Hz) and a simple three-wire installation. Included with the VariVib are a mounting bracket, new mirror-finish faceplate and knob. Suggested retail is $199.
