Up for sale is a phenomenal, hand-built KSR PA50 tube power amplifier, loaded with 6L6 power tubes. Built on March 3, 2025 (S/N 08-10444), this unit is in pristine, mint condition and comes packed in its original factory box with the power cable.
If you are running a high-end modeler (like a Helix, Quad Cortex, or Axe-Fx) or a dedicated preamp and want to ditch flat solid-state power for the real, organic feel and punch of tube iron moving air, this is the ultimate rig centerpiece. It handles everything from pristine cleans to crushing high-gain modern metal with incredible headroom and clarity.
Key Features:
- Power Section: Equipped with 6L6 power tubes and a 12AX7 phase inverter.
- Tone Shaping: Features dedicated controls for Top, Bottom, NFR (Negative Feedback Resonance), and Mastervolume.
- Voicing Switch: Hi-Fi / Guitar toggle switch to match your signal source.
- Bias Monitor: Convenient top-panel bias monitoring ports and adjustment for easy maintenance.
- Outputs: Selectable impedance switch (4, 8, or 16 ohms) with dual parallel speaker outputs.
It has barely been used and is packaged safely in its original box, ready to drop straight onto your board or rig setup. Ships out fast and safe!
