A mono power amplifier with a switchable 5-pole connection (Tetrode) and a 3-pole connection (Triode). It also has power, and you can use a 5-pole connection that has a heavy core in the mid-range to enjoy wild American sounds, or you can enjoy an elegant 3-electrode connection that is inferior in power to a 5-electrode tube but has low distortion. It's a fun car to use depending on the sauce and mood. You can see a feeling of use, such as appearance, dullness, scratches, etc. *Never test sound output or output operation without load.
