Vox AC30

The Vox AC30 was originally introduced in 1958 as “big brother” for the fifteen watt AC15 model, Vox's original flagship amplifier. The AC15 was powered by a pair of EL84 tubes, an EF86-driven Normal channel and ECC83-driven Vib-Trem channel, and rectified by an EZ81. The Original AC30, or AC30/4, had only a single 12 inch Goodman 60 watt speaker as opposed to the later, conventional twin 12” speaker configuration. AC30/4 sported two channels with two inputs – hence the “4” in the model name. There was only a single tone control in it as well. The power amplifier circuit had EL34 tubes and the preamplifier used an EF86, which was a pretty unreliable tube and could fail due to vibration. The amplifier had a tube rectifier.
