Some time ago I decided to build a balanced BA-3, but I never finished the build as it is of little use in the context of the rest of my system.
The two BA-3 boards are populated with matched PRP resistors, matched genuine Toshiba 2SK170/2SJ74 Jfets and 2SK2013/2SJ313 Mosfets, and ClarityCap (ESA 8u2) coupling capacitors.
Resistors R2 and elkos C1 and C2 are not populated on the boards, and possibly bigger heatsinks are needed for the Mosfets.
I never powered up the boards.
For sale at 80 euro a piece, or 150 euro for the couple.
