Hello Kai,
Thank you for the helpful suggestions, I will investigate the supply voltage levels. I examined the Z127 and replaced the filter capacitor and it seemed to produce 6.0V but did fluctuate when the deck is first turned on. The noise happens on channel II only and is mostly a upper frequency buzzing sound that decreases in pitch and lasts for about 1 second, perhaps a second and a half.
I have found another problem, the small red leaf type switch that is activated by the "start" button is missing the "U" shaped spring. Can anyone tell me the manufacturer of this switch, please? Or help me source a replacement?
Thank you!
Regards, Ken
