Re: Nakamichi Soundspace 5 - headphone works normal, both speakers volume very low at
My DMM will show minimal of 3-digit number like 11111, 111, 011, 001, etc. So 1Ω will be 001 and open will be 1.
OK. Voltage check means power-on and take readings would be like what I reported in post #30?
Q504: pin1 0v, pin2 0v pin3 0v
Q505: pin1 11.9v, pin2 0v, pin3 0v
Q506: pin1 11.9v, pin2 0v, pin3 11.9v (switching from radio to CD to tape same readings)
These readings were taken with black lead on chassis ground, and re lead on each of the 3 pins.
Can I test if Q506 is shorted Emitter to Collector by putting red lead on Emitter and black lead on Collector? Or how should I take the reading?
