The BorderPatrol S10EXD gives 8 Class A watts per channel from a single 300B output tube in single-ended configuration.

The combination of extended bandwidth married to excellent dynamics and a magic mid-range make the S10 both capable and musically communicative whilst the twin external power supply units give mono-block like sound staging, complete channel independence and bass control and dynamics not normally associated with amplifiers of this type.

Clear, clean, fluid, extended, tonally rich and natural are all adjectives used to describe the performance of this fine amplifier.

Marrying finesse and sophistication to dynamics not usually found in SET amplifiers, the BorderPatrol S10EXD is a fine musical transportation device.

Recommended loudspeaker efficiency >95dB/watt for best performance.

The BorderPatrol S10 EXD features inter-stage transformer coupling, twin external power supply units (PSU’s), hard wiring, a chassis made from copper and wood, and cryogenic treatments to the amp and PSU’s. Each PSU contains three independent tube rectified, choke input filter supplies, for 300B H.T. driver tube H.T. and 300B bias.
