[extra Quality] — Vox Ac4tv Schematic

The schematic includes three critical fuses to protect the circuitry: The VOX Showroom FS4 (Main): Located in the AC socket; FS1 (Heater): fuse protecting the tube heater circuit. fuse protecting the high-voltage "B+" rail. The VOX Showroom 4. Service & Technical Notes Vox ac4tv schematic

The "TV" in AC4TV stands for "Triode/Variable" or "Trainwreck-style Variable." The schematic shows a 4-position rotary switch that changes the impedance and voltage relationship between the tube and the output transformer’s primary. When you switch to 1W or 0.25W, the sound remains surprisingly good because of how the screen voltage is lowered. vox ac4tv schematic

The Vox AC4TV schematic reveals a streamlined Class A tube circuit designed for classic British chime and modern high-gain flexibility. Unlike the 1961 original that featured an EF86 pentode, the modern AC4TV (produced 2009–2016) utilizes a 12AX7 preamp and an EL84 power tube. The AC4TV circuit is divided into three primary stages: The schematic includes three critical fuses to protect

In the world of low-wattage tube amplifiers, few models have garnered as much cult status in the modern era as the . Released as part of Vox’s "Classic" series in the late 2000s, this 4-watt, all-tube combo amplifier captured the essence of the legendary Vox AC30 but in a bedroom-friendly package. With its signature top-boost tone, a unique attenuator that switches from 4 watts down to 1 watt and even ¼ watt, the AC4TV became an instant classic for home recordists and apartment dwellers.

A unique feature of this schematic is the built-in passive attenuator. A rotary switch allows users to select between 4 Watts, 1 Watt, and 1/4 Watt by engaging a resistor network that scales the output power while maintaining tube saturation.
