    Description

    19 March 2019 : the boards are now in
    yellow colour
    . Circuit and function/performance are exactly the same.
    This is an assembled buffer board using JFETs 2SK246/J103 as input. They are connected in cascode topology with another two low noise Toshiba BJT 2SA970/2SC2240 respectively to enhance linearity and extending the bandwidth of operation.
    The buffer board can be used as a building block in the audio path, such as a buffer in between the digital audio source and the preamplifier, or even as a preamplifier( gain of 1) by adding a potentiometer at the front.
    PCB dimension: 60mm x 30mm.
    The board requires a +/-15V DC power supply. Current consumption would be decided by the loading.
    We do air shipping worldwide at US.00. We welcome combine shipping.
