After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in preparation for SPICE simulation. The availability of hierarchical blocks for ...
Guitar virtuoso Paul Gilbert has replaced his traditional tube amplifiers with a pair of Fender Tone Master Twin Reverb digital amps for live use. The move marks a notable shift for the shred pioneer, ...
The K2-W vacuum-tube op amp has an LTspice-simulated open loop gain of 27,000. The modeled K2-W input impedance is >100 MΩ. The LTspice modeled result shows 1.00 nA of input current. Early SPICE ...
