VALUE!  An All Tube Practice Amp! Way back in 1961, VOX rolled out the AC4 amplifier. Nearly fifty years later, VOX is pleased to announce the AC4TV – the all-tube practice amp with remarkable self control. This up-to-date Class A version retains the distinctive EL84 power tube of the original and features a 12AX7 powered pre-amp, all driving a custom-made Celestion 10 inch speaker. The sophisticated sound is unmistakably VOX, delivering that distinctively British top-end tone. R$399
