Item DUK35PAH
These Vintage Dukane Model 1U460A PA amplifiers make absolutely great Harp Amplifiers because of the Great Fender Bassman Like Tone they produce.  This particular amplifier has been modified for Harp and the power supply capacitors have all been replaced with new capacitors.Additionally, the original XLR inputs have all been replaced with 1/4" input jacks and the wiring has been modified for High Impedance microphones.
 There are 3 input channels with separate volume controls for each channel.  Each channel has a different value preamp tube with different gain levels (Ch1-12AU7, Ch2-12AT7, Ch3 12AX7).  Consequently, each channel has more gain than the previous channel which makes this a very versatile amp for use with a variety of mics. The Amplifier is in perfect working condition and has been thoroughly tested and has worked flawlessly without fail every time.
The tubes are all in excellent condition (3-12AU7 tubes, 2-12AX7 tubes, 1-12AT7 tube 2-6L6 Power Tubes, 1-5U4GB Rectifier tube.   All mic channels and all other controls are working perfectly.  You will also appreciate the presence of separate Bass & Treble Controls!  The Bass control is setup in reverse (counter-clockwise increases the bass) and increases normally up to about 8 but the increase from 8 to 10 adds an enormous amount of bottom end which is perfect for Harp.
  As you can see in the pictures there is a grounded 3 prong cord and a fuse to protect the amplifier in the event of a power problem.
  At the back of the amp is a Speaker Jack (1/4") and the Speaker Impedance can be easily set to 4 or 8 Ohm Speaker Loads by simply moving the selection wire to the appropriate terminal.  There are 3 microphone inputs (1/4") on the back of the chassis as well.The 35 Watts of power is sufficient to power a variety of speaker loads.
The amplifier measures 19 1/2"x 9 1/2"x 8" and it weighs 25 pounds outside of the box.  Most of the weight is from the Huge Power Supply Transformer and Output Transformer which are necessary to provide a good constant output at the Bottom End and this amp definitely delivers there as well as throughout the Harmonica Range
