Hi,
i am kind of new to this things and have started to build a dual mono Buffalo II.
so today i powered up the 2 palacids and 2 Placids bp. No smoke!!! :) Led glowing.
So i measured the in and output voltages on the placids. Input is nearly 10 V Ac on both placids (toroid 2x9 V 15 VA) . but output is 1st: 8.51 V dc and 2nd: 4.63 V dc.
All other values of resistors are the same. the variable Resistors are set to VR1: 100 Ohms and VR2: 10 KOhms as stated in the manual. other parts seem to be in right place.
so i stopped here. what may be wrong?
thx
Branko

Hi,
found the problem. I misplaced the QN1 and QP1 parts (on placid with the higher output). after changing them to correct position everything was fine.
thx
Branko
