The 2UBES VTX is a modern adaptation of a classic 60's push-pull mic preamplifier design from a vacuum tube recording console, using custom designed audio transformers and controlled remotely via WiFi. It has two modes, "Clean" and "Glow" which changes the first stage plate load from passive to active. "Clean" is a classic honest Triode sound. "Glow" mimics a Pentode tube for something more retro. Two useful sounds. Push-Pull sounds different than single-ended tube designs.
Motorized Potentiometer provides smooth, transparent remote gain adjustment.
