Luxman r-1035

Hi,

I restore a Luxman R 1035 (It's the R 1030 with more watts). I changed the capacitor and the rectifier diodes on it and I have a problem :
when I turn it on, I can ear a big noise on my loudspeaker

. I hoped that the modification I made on it will erase this noise but not.

I need some help.

Thanks.

Hasnt got the R1035, but it has R1050 & R1070, so maybe these will help.

Did you get all the diodes & capacitors around the correct way when you replaced them.
Is the noise on both channels. Was the noise there before you srarted, or have the changes you made introduced the noise

It's ok, the problem came from the big capacitor. I still have something but on all my power amp, I think it's the house.
