BP-255 All-FET Super Shunt Regulator

BP-255 is a dual, wide-band, low-noise, shunt regulator. It is an ultimate regulator specially designed to use with audio stages such as line amp, I-V converter, and phono preamp. There are two versions of BP-255.
Version I is for high load current (200-350 mA) such as BP-320.
Version II is for low to medium load current (< 200 mA) and works well with BP-409 Line/Headphone Amp, I-V converter.
We highly recommend using the BP-255 Super Shunt Reg. with our
BP-320 and BP-409 modules!
