Need help with ML-9

Hi y'all!

I'm trying to understand a problem with my ML-9 amp + renaissance 90 speakers.
Yesterday, at about 40% of max volume the music system suddenly stopped and I noticed that the ML-9 has switched itself off - the power button was in OFF position. When I try to switch it on, it switches off immediately.

How can I determine if this is a small problem, maybe I need to change a fuse or a more serious issue?

Thank you in advance 🙂

Hi Miranda,

Welcome to the forum!

I was hoping an ML owner might respond. I'm being a bit pessimistic, but your symptoms seem more dire than a simple fuse, since it's appears that the amp enters a protection mode each time you cycle the power switch.

Do you have any repair experience? Any test equipment? I did a brief Google search and could not find any factory service manual. There are a few DIY attempts at drafting partial schematics.

How did you wish to proceed?

Good luck!

Steve
