Our version of the classic Marshall JTM-45 amplifier, circa 1965. The JTM45 (Marshall's first amplifier) was Jim's version of Leo Fender's 5F6A Tweed Bassman amplifier. The circuits were nearly identical, but the JTM45 had a beefier power supply, and when used with KT66's & a 4x12 cab, this amp had a British voice all it's own! A glassy top end with warm & creamy midrange tones makes this amp desirable for many genres of music, especially classic rock & blues. The slower rectification from the GZ34 adds a slight sagging/smoldering quality to the tone which allows the player to really dig in and make her rip & sing! Like most 4 input Marshall style amps, you can bridge the the 2 channels for slightly more gain and control.
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, The USA made JTM45 style Power Transformer, Output Transformer, and 40-18059 (20H) choke. 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.
