 Our version of the classic Marshall 1987 Lead 50W amplifier, circa 1969. Commonly referred to as the "Plexi," due to the plexiglass faceplate. Unlike it's predecessors the JTM45 & JTM50, the plexi used solid-state rectification and a larger power supply for slightly higher voltages, and tighter/punchier tone. Note: The power transformer included in this kit does have a 5V winding if you would like to use a tube rectifier. Like most 4 input Marshall style amps, you can bridge the the 2 channels for slightly more gain and control. The overdrive is rich, crunchy, and filled with subtle harmonic undertones. The tone of this circuit has been heard on countless rock albums from 60's through the 90's. Used by Jeff Beck, Eric Johnson, Yngwie Malmsteen, Pearl Jam, and countless more, the 50W plexi is truly a legend! The kit includes Mallory 150 series (or optional Sprague Orange Drop) Coupling Capacitors, JJ and F&T Power Supply Caps, Sprague Atom Bias Supply Caps, High Quality Carbon Comp Resistors, Alpha Potentiometers, Turret board, Marshall style Knobs, Belton Sockets, Cliff Jacks, NKK Impedance Selector, Fuse Holders, Power Cord, Power Transformer (US18033), Output Transformer(US18025), and 40-18059 (20H) choke. All the transformers are made in USA! The power transformer has multiple primaries 120/220/230/240V. The output transformer has outputs for 4, 8, & 16 ohms. We will also include all the Cloth Push-Back Wire you need to do the job. CHASSIS, FACEPLATES, AND CABINET AVAILABLE BELOW! Warm up that soldering Iron!!!
