Thank a lot for your thoughts and advices. I was already thinking about contact Luxman, but in fact maybe the repair will cost too much. I'll try contact them and see what they suggest me to do. Or maybe better, I'll think of some other amplifier so replace the Luxman.
Thanks again.
Hello everyone,
I have a Luxman L-5 that I used with Celestion ditton 44s until a few years ago when the amp broke.
The problem is that it goes into protection after a short time it's on, making quite a loud noise on the right speaker, after which it stays with the red light flashing endlessly...
