SpectraSound - Replacement Leslie Amplifiers

Powerful Amplifiers for Drawbar Organs and Drawbar Clones


SST-1122 Mark II Solid State Amplifier

The 100 Watt Replacement Vintage Rotary Speaker Amplifier. Covered by our 2 year Exchange Warranty.*

Finally! Someone has created a Solid State amplifier that has the warmth of a tube amplifier.

When you play a vintage drawbar organ and rotary speaker like a model 122 or 147, the tubes in the speaker’s amplifier are part of what makes that sound warm. For years, solid state amplifier makers have been trying to duplicate that warm sound of tubes. They have even tried adding a preamp tube inside the circuit to help achieve a warmer sound.

The SpectraSound™ SST-1122 Mark II Amplifier changes that. We have spent years developing and testing our new amplifier, making sure it has the warm sound of tubes. You can now have the power and reliability that you get from a solid state amp while giving you the warmth of tubes.

Drawbar Organ Clone owners no longer have to use special adapter kits to connect to vintage rotary speakers or buy add-on effects boxes to get a warmer sound from a new solid state rotary speaker cabinet. With the new SST-1122 Mark II you save money and extend the life of a vintage rotary cabinet.

Vintage Tonewheel Organ owners can now upgrade their rotary speaker cabinets, as well. You will need a qualified organ tech to install the correct connector kit or modify the organ to work with the 11 pin standard.

*2 Year Exchange Warranty. We are so confident about our amp that it's covered by our 2 Year Exchange Limited Warranty. If the unit fails we will exchange it. We will provide you a copy of the warranty upon request if you would like to know the limitations of the warranty.
