1980s Vox AC30 Top Boost Vintage Tube Amp, Rose Morris UK w/ Celestion Blue Speakers


+ shipping

Up for sale, a 1980s Vox AC30, fully serviced and loaded with a pair of Celestion Blue alnico speakers. A relatively rare iteration of the AC30 platform complete with Top Boost circuitry, this amp was produced in the UK by Dallas Arbiter for Rose Morris. Morris had purchased the Vox brand in 1978, and Dallas Arbiter continued production of the AC30 for Rose Morris under the new "Vox Limited" banner.

A notably gigworthy and faithfully designed AC30, this amp retains the traditional  six input, three channel design just like the iconic AC30s made by JMI in the early '60s. This Top Boost equipped model features a pair of Celestion Blue alnico speakers. Perfect for replicating the touch-sensitive, glassy cleans and overdriven sizzle and roar of the quad of EL84 power tubes, these speakers have ideal wattage handling and power for a dynamic, rich response.

The amp boasts individual Volume controls for each of the three channels, as well as Vox's signature "Tone Cut" treble roll off knob, with Treble and Bass controls that comprise the Top Boost portion of the circuit. Round things out with Vox's distinct footswitchable tremolo/vibrato effect and you have an amp that truly has a feel, response, and layout consistent with Vox's golden-era AC30 design.

The circuit has been thoroughly serviced, balancing originality and functionality, with the original power transformer intact and a modern USA-made Mercury Magnetics output transformer and choke, both wound extremely faithful to Vox's golden age design to properly replicate tone and output characteristics. The circuit is mounted on a trio of brown PCBs, designed by Dallas Arbiter to be more reliable than the PCBs used on earlier Vox amps from the Stolec Industries era in the previous decade, and the circuit is chock full of vintage Mullard "tropical fish" capacitors.

The speakers are a new pair of Celestion Blue alnico magnet 12" drivers, more faithful to the early JMI Vox sound than the speakers used in the '80s. The amp retains its original black basketweave tolex with gold piping and brown lattice grillcloth. The grillcloth is a bit loose in its appearance, yet firmly adhered on all edges, and there are some scuffs and typical small tears in the tolex along the cabinet edges, along with a few non-factory mounting holes on the top front edge of the cabinet. A split in the finger-jointed cabinet at one of the top edges has also been repaired. All of the original hardware and plastics are intact including the handles, two-pin corners, and large Vox badge. The "Vox Limited" badge is largely intact on the back panel too. The dark blue/gray faceplate has clean gold silkscreening and its full complement of chicken head knobs.

The amp comes complete with its original wedge footswitch to engage the Tremolo/Vibrato.
