AVM Tube-OUT Tube Module for Ovation PA 8.3

The AVM Tube-OUT is a retrofit module for the modular AVM Ovation PA preamp that fits the output stage with AVM's own 803T tubes instead of transistors.

Instead of having to decide between transistor or tube sound for your whole system, with the PA 8.3 you simply swap the output module – solid-state and tube both fit into the same preamp, and you switch depending on mood or genre. The 803T tubes are an AVM in-house development rated for several tens of thousands of hours of lifespan, so not a wear part you have to replace every few months. If you've never heard the difference live: it's rarely dramatic, but often exactly the touch of warmth you didn't know you were missing.
