Product Details


Whats Included



The Hiss Killer Kit suppresses hiss at a Wurlitzer electric piano's 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.)

*200A Hiss Killer Kit will contain two sets of TR15 and TR16 transistors marked “EARLY and “LATE”.  Late model aux-out production started at serial #102905 (schematic #203720-S-3).  If your piano’s serial number falls before this, use the EARLY set of transistors.  If your piano’s serial number is later, then use the LATE set. Select your model Wurlitzer from the drop down menu to ensure that you receive the correct components for your amp.

No instructions included but I'm pretty sure there's one online. Would be nice to have a paper copy along with the electrical components. Still need to install this but, I'm excited to quiet down the Wurly.
