View attachment 56864 View attachment 56864 I got a nice WM-D6c that is in very nice condition. 99% mint. Unfortunately the speed is much too high. The CX20084 is 100% (1,65V on pin 5). The base of Q601 gets 5,4V from pin 15. The emittor is 6 V and the collector should be 2,35V, feeding the motor. But it is also 5,4V, so the motor runs too fast. So it looks like the Q601 is bad. Is that a common failure?
How's C609? I had a problem with mine, yet I changed a lot of caps. On mine changing caps fixed it. I can recommend one of these (LCR cap tester, tests ESR, can even do some in circuit work. sort of): https://www.amazon.se/transistortes...-bakgrundsbelysning-kondensator/dp/B0B7X35BBT
