Disassemble MS275

Hi!

I had to replace the gain trimmer on my MS275 because it is too old (I have the gray version of that amplifier, 1990) and sometimes, specially after a road pit, I got noise and rustle until I move it.
I tried to unscrew mosfets and four screw on the board but it seems to don't move..
Someone has a wiki or how-to disassemble that amplifier? I'm scared about break it!

Thank you!

Welcome to this forum.
This will give you a good start;

Please remember that when you have no experience with these type of repairs, changing the gain pot in a MS-amp is NOT a job suitable to start with.

Use the search function on top of the page to find more info; we have shared a lot of knowledge about working on these amps already in the past.
GOOD LUCK.

Thank you very much! This is a good start point

Don't worry about my skill with solder and electronics.. I'm pretty able with that and I hope I will not have problems..
