Hi, I am a diy .person and have replaced the Capacitors of my two Cyrus 2 amps. I also use a PSX and they drive my magnepan speakers well.
I like to expand my knowledge about these amps.every time and now I am planning to check the bias current. According to the service manual you must measure across R107 and R108. Does this mean measure between 2 legs of the resistor? Can anybody tell if that's right?
Greetings, Wim

Correct.
“Across the resistor” will measure the DC voltage change from one side to the other (which is turned into heat) and then you apply Ohm’s law, I = v/r , and as you know the v and r, I (current) can be calculated.

Thnx for your quick response. So I use my DVM to measure this with the power on and no speakers/ sources attached?
