I tried the Stock F5, now the Cascoded F5, I'm going to try the Balanced F5 next. I'm selling my Cascoded F5 board. It functions perfectly.

I used BC546 and BC556 for the Cascode. I used Panasonic 3W 150 ohm paralleled x 3 for feedback resistors. Two channels on one PCB. EPCOS 4.7K NTCs. Matched 2SK170BL and 2SJ74BLs.

$39 plus $5 shipping in the USA.
