need help- marantz reciver model:sr-50
Don't know if this helps, but the SR-63 and SR-82 had this problem resulting
from a small capacitor bad in the power supply area. Can't quite remember the value - I think it was 2.2 uF. It was a small yellow electrolytic. It was used to lightly filter a dc line, then this reference was used for the sharp cut-off function at power-off. When the machine is turned off, it cuts off the speaker relay quicker this way. With the bad cap, the protection just stays engaged. Mark Z. -- Please reply only to Group. I regret this is necessary. Viruses and spam have rendered my regular e-mail address useless.
