Anyone have this kind of problem with their amp?
I own a Classe CAP-101 integrated amp that I bought used about 10+ years ago. Recently, it's developed a problem where the right output channel doesn't operate. Sometimes, the amp works just fine. But at other times, the right channel won't operate when I power up. At still other times, there's no issue when I power up, but the right channel will stop working after a variable period of time, sometimes ten minutes and sometimes thirty or even more. Occasionally but not frequently, after the channel has stopped working, it will resume working after a while, continue to work for a time but then may revert to not working. When the channel stops working, turning the amp off and restarting it, and/or unplugging and replugging it, does not restore operability. I've checked and re-checked my connections (bare wire) without any effect
It's not my other equipment, because I've inserted another integrated without any issue.
I've taken it to a repair shop but the tech couldn't replicate the problem, so he couldn't diagnose it.
In the past, when I've contacted Classe customer support by email about a previous issue or with a question, I've never even gotten a reply.
Any thoughts/advice? Thanks in advance.
