Uber-rare, one-year model tube amp by Vox/Thomas Organ utilizing mostly JMI AC10/AC15 componentry including transformers, cabinetry and the highly-coveted, UK-made Celestion 7724 10” speaker.
This example is all original save for replaced three-prong power. It is generally recommended to replace the main power filter capacitors in vintage amplifiers. This amp functions exactly as it should with all of its original Vox tubes and electronics, but comes with NO warranty or guarantee of it’s electronic functionality. Includes reverb/tremolo foot switch. This is a gorgeous sounding, low-powered combo amp. Certainly one of the nicest examples you are likely to find.
Here’s the Cambridge Reverb V-3 story from the Voxshowroom website…
“Introduced in 1965, the original Cambridge Reverb was an all tube amp with circuitry inspired by the JMI Vox AC-15 amplifier. The seven tube circuit featured three ECC83 preamp tubes, one ECC82 preamp tube, two EL84 output tubes, and one EZ81 rectifier tube. The single channel amp had three inputs, reverb and tremolo.
Like the British AC-15, the 17 watt RMS tube output stage of the Cambridge Reverb V-3 was cathode biased. The preamp used a slight variation of the "top boost" circuit from the AC-30. Despite the American lineage of this amp, it oozes with the clean, chimey tone of British Vox amps. When overdriven, the amp breaks into a sweet violin-like tone.
While most V-3 Cambridge Reverb amps had a black control panel, some early amps had a silver upper control panel and a black rear control panel as shown in the image at left. Some V-3 Cambridge Reverb amps had an oval hole in the rear panel while others had a split rear panel.
Thomas Organ imported a 10" Celestion speaker from the UK for the Cambridge Reverb V-3. The 10" Celestion was replaced with a 10" "Gold Bulldog" speaker made by Oxford Speaker of Chicago IL in later production.
The control panel featured two instrument inputs plus volume, treble, bass, tremolo speed, tremolo depth, and reverb controls. The lower control panel included a third instrument input plus external speaker and foot switch jacks. The power switch featured a standby function and dual pilot lamps indicated whether the amp is in "standby" or "operate" mode.
The cabinet of the Cambridge Reverb V-3 was constructed of fir plywood and was covered in a basket weave pattern vinyl. A two spring Hammond Accutronics full sized reverb pan rested on the inside bottom of the cabinet. A horizontal Vox logo, one pin corners and a strap handle with gold end caps were featured.
An amp head and 2x10" speaker cabinet piggy back version of the Cambridge Reverb was additionally offered as the "Berkeley Super Reverb."
The 1965 US Vox price list indicated that the retail price for the Cambridge Reverb V-3 and accessory two button foot switch was $189.90. Adjusting the 1965 retail price of the Cambridge Reverb V-3 for inflation to the 2010 value of the dollar, this amp would cost $1278 today.”
Of course the rarity of these brings markedly higher prices.
