Jazz 100 is designed on basis of 805A Power Tube. It outputs 46 watts per channel operating in Single Ended Class A. 

All tube Integrated with Mullard 6JC6 and 6SN7 voltage amplification stage, 6L6 driver stage, and 805A output tubes. For Driver stage we used 6L6 but you can also easily use EL34, 6CA7, 5881, 6550, KT88, KT90 etc for replacement that you can enjoy the different sound performance.  

Three pairs of Line Inputs, one pair of Bluetooth Input are located on the rear panel of the amplifier.

Speaker terminals for 4 and 8 ohm speakers are located on the rear panel of the Amplifier.

Taking advantage of customized Output transformer Jazz 100 provides Headphone Output that can drive most of the headphones in the market.

Dual Function Meters: Double meter design, retro and eye-catching, a professional power meter that rhythms with the power. You can feel the beauty of the music rhythm. Furthermore you can also use the Left Meter for Bias Adjustment and Monitor with Meter Switch on top plate. 

User bias controls for 805A are available for bias adjustment on the top plate. 

Hum balancer for 805A tube is accessible on the top plate for easy adjustment of the hum level of the Power Tubes.

High Voltage Fuses are used in the amplifier for protection. In case there were failure of tubes the Fuse will react first that you can know easily where the issue is. 

Negative Feedback Selection is available on the top plate with NFB Switch that you can choose between High and Low NFB to enjoy the different sound outputs of the Jazz 100 tube amplifier.
 

Anodized aluminum front, fully vented chassis with excellent gorgeous finish, hand-made construction with the finest point-to-point wiring.

Premium Parts: Alps volume control, Porcelain Tube Sockets, Audio grade capacitors and carbon film resistors, Toroid transformer for power supply, Wide bandwidth EI output transformer, etc.

Soft-start circuit and High Voltage Delay to protect the amplifier for an extended life of the tubes.
