Hello all!
Help about the schematics for JFET buffer .
Signs need schematic JFET buffer that uses a symmetric power supply Us=+/-(9...12) Vdc.

SE or push-pull (complementary) ?
What's the maximum voltage swing at the output ?
What's the input impedance of the next stage ?
Something like this (post #73):

This one is hard to beat in sound and measurement, designed by JLH back in the 80s. Use 2sk170 and 2sj74 as the Jfets but the ones shown and others will also work but with lesser performance. If you bias the slave bjts hard it will happily serve as headphone amp too with very low distortion for phones with as low as 100 ohm impedances.
Look at figure 3 or the buffer at the bottom of this page. http://www.tcaas.btinternet.co.uk/jlhphones.htm
