My transformer has just stopped working. was fine 24 hours ago- is there a trip switch? Model LV300/LV300T

There is no trip switch, or reset button for ML series Intermatic/Malibu power packs.
Your question shows LV and not ML, so there might be a different model number, but generally power packs are not a repairable item if power pack is broken.
Add a comment with in-focus photo of your timer for possible identification difference between ML series and your power pack.

My ml600tw timer stopped working. How do you replace the timer? I took screw out by timer but I cant pull timer out. Is it held in another way?

You posted under Intermatic/Malibu ML series power pack.
There are no replacement clock mechanisms or timer modules for ML series power packs.
If you found a replacement clock motor source, add a comment add a comment here so others can benefit. If you find a way to repair clock motor, also add a comment.
Many people have same problem and will benefit from your discovery.
To work around problem, buy cheap plug-in timer, set power pack to override, and then plug power pack into cheap timer.
ML series has 5 year limited warranty.

Power amp for pa system stopped working

Sounds like you have a power supply problem in the amp. I am assuming the fuse you are replacing is intergraterd into the AC connection. You need to dig deeper. If you are not an electronics person you will need a tech.
