Fender Vibrolux Reverb #A 02015 |
The Vibrolux name was first applied to a Fender amp in
1956. In that year, the Vibrolux became Fender's second amp
to feature (what Leo called) vibrato, which was
first introduced the previous year on the Tremolux.
That first Vibrolux, which was essentially a
Harvard with tremolo, used two 6V6 output tubes to produce
10 watts of power through a single 10 inch speaker.

In 1961, a new Vibrolux, covered in brown Tolex, replaced the
original tweed model. The output section of the new version featured
two 6L6 output tubes and a larger, 12-inch, speaker.
A black face Vibrolux, covered in black Tolex, followed in the
summer of 1963. The speakers were upgraded again to two 10-inch Jensens,
as in the amp pictured here. The Vibrolux Reverb replaced the
Vibrolux in the fall of 1964. The circuit design of the
black-face Vibrolux models are virtually identical to the design
of the contemporary Deluxe models, with the following
differences:
Comparison of Vibrolux and Deluxe Amps
| Feature | Deluxe | Vibrolux |
| Speakers | 1 12-inch | 2 10-inch |
| Output tubes | 2 6V6 | 2 6L6 |
| Bias Voltage | 420 Volts | 465 Volts |
The tube complement of the black face Vibrolux Reverb includes
- 4 12AX7 preamp tubes
- 2 12AT7 lo-gain preamp tubes
- 2 6L6 power tubes, and
- 1 5U4G rectifier tube.
The speakers of the amp pictured above are two ten-inch Jensens,
date-coded 220540, implying a manufacture date
in late 1965. The cabinet is finger-jointed, solid pine, covered in black
Tolex. All electronic components have been connected by point-to-point
wiring and soldered by hand.
