I need some help with finding a techcenter that can repair my Integrated Amplifier FA670.
After switching on, the amp provides a distorted signal for the first 30 minutes. After approx 30 minutes the sound normalizes. Switching to another source has the same effect. It seems as if the source selectors are no longer making good contact. The amplifier sounds very good still (made in Japan-Marantz ?)
Will a good internal cleaning job do the job ?

Is this behaviour similar each time you use the amp ?
If so, I wouldn't suspect its switches. So a cleaning job will not fix it.
You might have a defect in your powercirquit. Perhaps getting better when it warmes up.
You could take this amp to our central repair workshop in Krimpen aan den IJssel. (All estimates for repaircosts are free.)
Bedankt Herman,
Ik zal zo spoedig mogelijk een bezoek aan het service centrum plannen.
