I've seen the other posts here about how to adjust idling current on an 820, but the posts and service manual are not completely specific in what test points to measure.
The manual says to turn VR701 and VR702, so that the voltages between TP1 and TP2, TP3 and TP4 become rated value as shown in right hand side (8+-2mV).
So does this mean measure current between TP1 and TP2 and turn VR701? Those 2 test points are next to each other, while TP3 and TP4 are legs of output transistors.
It seems to me that I should turn VR701 while measuring voltage across TP1 and TP3, and
turn VR702 while measuring voltage across TP2 and TP4. Can someone confirm this for me. Thanks.
