Hi,
I got a NAD 7100 receiver for repair. I dont get sound from the left speaker (it doesn't matter speaker group A or B). I don't have sound on the left channel when I plug in headphones too. Balance and volume rocker seems to be OK.
I did also checked the "braze point (?)"... But they seems to be ok (I don't have bad contact when I tap with the rear from a screwdriver over the circuit board).
What I did see: When I tap with one finger the bridge between "pre and main amp" from the left channel, I can hear a buzzing noise from left speaker/left headphone channel. When I tap the bridge from the right channel are there no buzzing noises...
Anyone any ideas what that could be?
Many thank from Switzerland (excuse my english - I'm still learning)...
