Wurlitzer Hiss Killer Kit$30.00
Vintage Vibe offers a Hiss Killer Kit that suppresses hiss at a Wurlitzer eleactric piano's speaker and aux output.
The Hiss Killer Kit suppresses hiss at a Wurlitzer electric piano's speaker and aux output. Model 140B's are notorious for noise and although improvements were made with the 200 and 200A models, these pianos often exhibit an unwanted and annoying hiss at the aux output. Therefore, we have designed versions of this mod for 140B, 200 and 200A amplifiers. These are not amplifier rebuild kits and they will not remove hum (rebuild kits are available: 140B , 200, 200A; they are designed to remove hiss and due so quite effectively.)
