Alternate View WDPre3 Valve Preamplifier
Ref: WDPRE3

A brand new and innovative valve preamplifier featuring low impedance drive to suit any power amplifier. This 5 input line level preamp is essentially an SE triode power amplifier in concept. WDPre3 uses an ECC82 double triode arranged as input voltage amplifier and power output amplifier stages, the latter driving large 20:1 output transformers.

The use of output transformers not only provides a low impedance drive but also avoids any possibility of slew rate limiting in the output stage making the performance independant of the capacitance of interconnect cables. Thus the WDPre3 will successfully drive long cables connecting to power amplifiers near the speakers if you wish. Twin pairs of outputs allow easy connection to power amplifier and headphone amplifier, or bi-amping.

Another advantage is due to the interwinding screens used in this advanced design. Effectively the primary and secondary windings are isolated from each other allowing us to break the ground connection between preamp and power amp thus avoiding the possibility of hum loops.

Input selection utilises high performance miniature relay switching on the rear panel, optimising the input signal path. Internal connections are made via Soniqs twin core and screen interconnect cable to the Alps Blue Beauty potentiometer.

External dimensions with valves: W135 x D310 x H80mm. Weight: 3.5kg
