TR-Valkyrie Hot Rod Analog Synthesizer

Trogotronic TR-Valkyrie

The TR-Valkyrie from Trogotronic is a vintage test oscillator repurposed to create maximum sonic mayhem. Its high-voltage quad tube oscillator has been retrofitted with vactrol-based CV inputs, allowing for frequency modulation of the internal oscillator, as well as turning it into a powerful ring modulator or a raucous, nasty preamp. And even when silent, its dual power lamps and large front-panel knobs make it an attractive addition to any gear pile.
