S10 EXD

About the S10 EXD

The BorderPatrol S10EXD amplifier provides 8 Class A watts per channel using a single 300B output tube in a single-ended configuration. It combines extended bandwidth with excellent dynamics and a rich mid-range, resulting in a clear, clean, fluid, tonally rich, and natural sound. The amplifier includes twin external power supply units that offer mono-block like sound staging, complete channel independence, and superior bass control and dynamics uncommon in amplifiers of this type. It features inter-stage transformer coupling, hard wiring, a chassis made from copper and wood, and cryogenic treatments applied to both the amplifier and power supplies. Each power supply contains three independent tube-rectified, choke input filter supplies for the 300B high tension (H.T.), driver tube H.T., and 300B bias. The recommended loudspeaker efficiency for optimal performance is greater than 95 dB/watt. This amplifier is designed to marry finesse and sophistication with dynamics not usually found in single-ended triode (SET) amplifiers, making it a fine musical transportation device.
