Hello i have a problem with my 636.
the faders is having a (ground) problem i think,on every channel.
When i use the pots its no problem.
i can record with no hum and noize, but when i play the recorded material ive got this irritating problem on every channel when i use the faders.
where can the broken part be ?
my teory is that it can be the power supply
