Take the power switch out, then apart. the contacts have fused together. Common problem in this switch. A suitable replacement is available on Mouser, but not really required. There has been a update to the switch wiring, put out by Classe. This may be the open ended wire you are seeing.
Classe DR-8 Schematic
Hi All,
Got my hands on a Classe DR-8 recently and enjoy the sound, but my particular specimen has a few quirks:
- Power switch doesn't work. Have to remove the power cord to turn it off!
- There's a wire that isn't attached to anything. A red wire runs from underneath the small PCB beneath the IEC jack towards the front of the amp and is twisted with the black and orange wires that run to one of the bridge rectifiers. It is much longer than the wires that go to the rectifier.
- New binding posts. Nice posts were installed, but whomever did so also removed the cap and resistor across each channel. A picture I've seen has a yellow film cap and black Dale resistor across the positive and negative terminals of the output for each channel.
So, I would like to get my hands on a complete schematic if possible. I've found a service manual online, but it only has the schematic for the main PCBs.
Barring that, I would love to know where the stray wire is supposed to attach inside and what the values of the cap and resistor across the output are.
Thanks in advance for any help!
Jeff
