Hi, I need an advice about film capacitor on preamp board.
On youtube video there is tutorial to replace old capacitors with 470nf axial film capacitors, but this is for newer version of board. I have older version like @scratje describes on page 32, but he uses 220nf in combination with original resistor.
I already bought 470nf capacitor, so can I use it without original resistor, like on the video?
thanks

Hi, I'm trying to repair my system, I have a popping and noise problem, I read that it could be the db-15 port on the woofer, I disassembled it and I realized something strange, basically when the sk preamp It is NOT fixed to the frame, the system works perfectly, but when it is fixed to the frame I get these noises and popping

I tried to isolate the sk preamp from the chassis, putting plastic tape between the supports and the chassis, but nothing changes

to make it work well at the moment I have to have the sk preamp free in the woofer...

Do you have suggestions and ideas?
