Hello everyone,

I need the service manual or schematics for a Philips power amplifier : FA660/00R.

Thank you for your help !

Or, if you can help me to repair, i explain to you the problem :

When I plug a small loudspeaker, it got in protection. Since I test the amplifier the fuse burns. If I use a strong fuse, it snore and the two resistors and the two transistors surrounded in red on the picture become very hot.
The two transistors are A1264N and C3181N.

Because your loudspeaker are in 4 Ohms.
Try with 8 Ohms.

it's a warning use for Denon receiver for example:
"If you have 4 Ohms loudspeaker, after hour or if you increase your volume, the receiver can go in protection".

it exist small loudspeaker in 8 ohms.

Or test your "Power transformer". It possible it's tired ??
