The Fryette PS-100 Power Station is a 100-watt dual-mode reactance amplifier that combines a reactive load, a high-end power attenuator, and a tube power re-amplifier into a single portable unit. 

Key Functions

• Power Attenuator: Safely reduces the volume of high-powered tube amplifiers (up to 200W) down to whisper or bedroom levels without sacrificing dynamic feel or tonal integrity. 
• Power Booster: Amplifies the output of low-powered or "lunchbox" amps (like a Tweed Champ or Princeton) so small vintage or mini combos can keep up with a full live band. 
• Silent Reactive Load: Acts as a load box for silent direct recording into an audio interface or DAW using analog simulation or impulse responses (IRs). 
• Standalone Power Amp: Can be driven by modelers, preamps, or digital modelers using its built-in dual 6550/KT88 tube power block. 

Main Features

• Dual Footswitchable Channels: Features two independent sets of Volume, Presence, and Depth controls that let you switch between two different volume or EQ settings on the fly. 
• Post-Distortion Effects Loop: Adds a transparent, footswitchable effects loop to any amplifier—even vintage amps that don't natively have one. 
• Flexible Impedance Matching: Offers independent impedance selection (4, 8, and 16 Ohms) for both your amplifier input and speaker cabinet output to prevent mismatching damage. 
• Line Outputs: Includes balanced XLR and unbalanced 1/4-inch line outputs with level controls for direct mixing or recording

  This is a great tool, but I just don’t use it very often so I’m deciding to let it go. Priced to sell!
