In advance sorry for the english, i'm just a poor frenchy :)
I restore my first boombox thanks to this amazing board.
Oxeded lever buttons, power switch, source switch... most of issues have been solved.
I still got one: i'm unable to turn off right speaker, it still whispering.
I'm also unable to fine increase the volume at start. it jump with a loud sound.
Lever have been cleared many times with a french elec. contact cleaner.
It sound like a ground problem, (when a touch the lever, i got like small impulsion in the speaker) I have already check solders without success
A video of the problem :
Thanks in advance for your help
