About the SE300B
The BorderPatrol SE300B is an entry-level single-ended triode (SET) stereo power amplifier renowned for its transparent, detailed sound with exceptional bass control and a wide soundstage. It features a two-box design with the main amplifier housing two 300B output tubes driven by two 6C45pi driver tubes via interstage transformers, paired with an external choke-input tube-rectified power supply using GZ37/CV378 for the 300B, EZ80 for the drivers, and another EZ80 for bias. No negative feedback is employed, emphasizing purity and musicality. Reviewers praise its dead-silent operation, natural midrange, and ability to drive efficient speakers (>93dB/W/m, >6 ohms). Upgrade paths exist to EXD (improved transformers/drivers) and EXS (superior PSU) versions. Compatible 300B tubes include Electro Harmonix, EML, Takatsuki, and Western Electric.
