![]() The 1965 AC-10 Twin, shown at left, utilized yet another type of 10" speaker. The frames of both the Elac and Goodmans speakers were painted in the traditional blue color. The 1964 AC-10 Twin also shown on this page used two Goodmans "Power Range" 10" speakers. Vox equipped the 1963 AC-10 Twin shown on this page with a pair of 10" Elac speakers. JMI Vox catalogs from the sixties indicated that the AC-10 Twin amp was equipped with "two special 10 inch loudspeakers." This lack of specific speaker information left the door open for whatever "special" speaker might be chosen by Vox for future AC-10 Twin production. Eight "one pin" plastic corners, a "Ten Twin" grill badge, a Vox logo handle and three Vox logo air vents were installed.ġ963 AC-10 Twin Amplifier - Serial Unknown Black Vox grill cloth and gray control panels were now the norm. The cabinet was covered in black basketweave Vynide. Known as the "thick edge" AC-10 Twin cabinet, the top, bottom, sides and baffle were made from 3/4"īaltic birch plywood (see photo below and inset photo "C"). The final version of the AC-10 Twin cabinet was produced in late 1964. The logo, handle and grill remained unchanged but the brass vents were replaced with a new molded vent with a Vox logo. It had a "thin edge" cabinet with rounded rear edges (inset photo "B"). The next generation AC-10 Twin cabinet was produced in mid 1964 and shown on the amp at the top of this page. The only significant change was the replacement of the luggage style swivel handle with a Vox logo handle. It was similar in most ways to the original "thin edge" AC-10 Twin enclosure. It also featured the "thin edge" cabinet. The next version of the AC-10 Twin cabinet was produced in late 1963 and shown at right. The amp had a large Vox logo, brown Vox grill, a hinged plastic "suitcase" style handle and brass vents. After Vox phased out fawn vinyl in 1963, the smooth black vinyl that covered the Vox Continenal organ was used on the AC-10 Twin. The earliest AC-10 Twins were covered in fawn rexine vinyl. As it was constructed primarily of 3/8" baltic birch plywood, it earned the name of the "thin edge AC-10 Twin." The front and side edges of the cabinet were radiused, but the rear edges were square (inset photo "A" ). The earliest version of the AC-10 Twin was produced in 1962. The AC-10 Twin had the look of a slightly downsized version of the AC-30 Twin.Įven though the AC-10 Twin was only produced for a few years, the cabinet went through a number of revisions. You can view detailed pictures of the AC-10 chassis and learn more about its circuitry in the AC-10 "Under the Hood" web page. The tube complement included one EF86, one ECF82, one ECC83, two EL84 and one EZ81. Later models used a rotary switch for mains voltage selection. A remote "egg pedal" foot switch actuated the tremolo effect.Įarly models included a plug style mains voltage selector (see control panel image at top of page). The Vibrato channel had "Speed" and "Amplitude" (depth) controls. Vibrato was a bit of a misnomer as the AC-10 actually had tremolo, not vibrato. A single tone control rolled off the treble response in both channels. The AC-10 had a Vibrato and a Normal channel, each with two inputs and a volume control. The schematic was updated in September 1964 when 120 and 160 VAC mains voltage taps were added to the power transformer for export models. ![]() The circuitry for the Vox AC-10 was designed by Dick Denney and was published on Jennings service schematic OS/008, "AC/10 Amplifier No. The AC-10 "Super Reverb Twin," a separate AC-10 head with reverb, tremolo and a matching 2x10 speaker cabinet became available in 1963. The addition of a second speaker in the AC-10 Twin helped to bridge the gap in the Vox line between the single speaker AC-10 and the AC-15. JMI also added a second 10" speaker to the AC-10 in 1962 and created the AC-10 Twin. The AC-15 Twin was priced between the 1x12" AC-15 and the AC-30 Twin. Vox introduced a dual 12" AC-15 in 1962 by modifying an AC-30 Twin cabinet to accept an AC-15 chassis. The 34 watt, dual 12" speaker AC-30 Twin was perched at the top of the Vox line.Īfter the basic amp line was in place, Vox created a few new models from existing components. Next came the 10 watt, single 10" speaker AC-10, marketed by Vox to "the smaller group." The 17 watt, single 12" speaker AC-15 met the needs of the club musician. JMI introduced the 4 watt AC-2 (later known as the AC-4) as an entry level amp. No use on online auctions, eBay or Reverb.īy 1961, Jennings Musical Industries had laid theįoundations for a complete Vox amplifier line. ![]() © 1996 - 2023 The Vox Showroom, all rights reserved. ![]()
