Hi Paul,
this Polaris is mine, i already changed the panels & this works fine.
and yea, i can turn on the TUNE LED and get plus-or-minus, so i think the slider is fine.
The volume is always on maximum, i change it now through the assignable volume control,
this works. The master volume didn't work even before i changed the panels, i hoped that
this panel change might fix it.
If the problem is the transistor Q1, is it "easy" to change?
I got a little experience in soldering.
Thanks so far
cheers Harald
