Classe CA-2100 - LED turn red, Amp shuts down, LEFT side of the Amp is extremely hot!
My Amp, which is a Classe CA-2100, has been acting up. It has a status LED light in front that usually stays Blue, but lately, the left channel LED turns RED and it shuts down. Whenever that happens when I goto the Chassis, the LEFT SIDE is extremely HOT! Like super hot to touch. NOT the right side.
The company is in restructuring so I am trying to see if I could get any support, but being a computer engineer and knowing a few things about electronics, is there a way for me to test and see what component is failing? I have access to multi-meter to do some measurements if necessary.
That’s good couldn't see the daughter board in my pic https://hometheaterhifi.com/volume_12_4/images/classe-cap-2100-integrated-amplifier-inside-chassis-m... Still going to have to get to the underside of those emitters, if they aren’t +speaker Cheers George |
Me thinks you'll need a service manual It looks very tight in there to get meter probes on to the emitter resistors which I can't even make out. And there look to be blue trimpots all over the place!!, good luck finding the bias one with out the manual. https://hometheaterhifi.com/volume_12_4/images/classe-cap-2100-integrated-amplifier-inside-chassis-m...

He’s going to have to get a probe onto the under side of those emitter resistors, looks real hard, unless the speaker terminal works. Strongly suggest "insulated mini long hook-on probes", connect first then turn on, and visa versa. Also imhififan do you have an indication which of the blue muti-turn pots is the bias one for him?
