Hi there, this is my first post in the Yamaha forum.

I would like to share some pics of a small project I did lately.
Bought a CA-1000 II on ebay which was sold as a non working unit. I wanted a CA-1000 badly for quite some time and when I found this one on ebay.de, Germany (It looked okay, price was ok) I was very happy and ready for a challenge. (I am a beginner when it comes to repairing audio electronics...)
When I first turned on the unit, there was no sign of life at all. The first thing I found was a dirty on/off switch. Cleaning it and treating it with contact spray was enough to get the switch working. (Checked it thoroughly with a multimeter before mains etc..). Amp was still dead. At least I could hear the transformer hum. But no protection relay click.
right channel main amp removed, this is the faulty part as it turned out. One of the fuses was blown. So I started to look for trouble here.
more pics on their way...
