nice one they are hard to find but worth it, work great!!
small tip, wire up with aud_clamp and dont solder the small point 1 on the jtag qsb, bridge 2 &3 and leave the point to the small resistor alone, even better follow martinC's guide to preparing the qsb's
the resistor blows so easily and it f**ks up your front ROL, its not necessary and can give you a headache to fix.
