Hi I had a problem with low power on my 500X, front panel showed input gain was ok, I mucked about with all the knobs and switches on the back and when I flicked the uv light switch on and off and it exploded back into life, nearly had a heart attack (make sure volume level is not above no 2 😂😂)
Guess I need to book a service 🤔
Ah I just noticed last entry on this was a while ago but ha ho 😂
