    I am planing to use Toshiba TTC004B instead of KSC2690A. Cob is lower than KSC2690A (12PF - 19PF) and better hfe linearity.... and I prefer Toshiba rather than KSC/KSA .

    Small board is for +/-15V. Small one on the right is 5/20/30 sec timer board (PIC). For the electrostatic headphone, please refer the following forum. https://www.head-fi.org/f/threads/my-diy-electrostatic-headphones.498292/

    Thank you guys, To save cost for my future DIY projects, I am planning to make a universal power supply. Toshiba 6RA6 is not easy to find in JPN but we can find imported 9RA6 in US.

    JoeMat, Very nice! use LT1021 to the active battery is good idea. Keven, can you add extra pattern for the solid state input (LSK389 and 2SK170 x2) option?

    How is a bias voltage? Too high or low...? Bias voltage is from a same circuit but if diaphragms have a different tolerance.

    Buzzing noise when adjust VR1(2K) toward the R33 side. So I set VR1 wiper to R32 side to avoid buzz noise at the beginning. Both VR1 and VR2 affects voltage of Active battery but VR1 affects much less. I have no benefit from adjusting VR1 so I replaced VR1 (2K) to fixed 2K ohm register and center(Q17 Base) connected to the R32 side. And changed VR2(10K) to 9.1K fixed resistor with 2K pot. After replaced these, no more intermittent static noise when amp is heats up https://picasaweb.google.com/inuponken/T2#5566996623938911634
