I am trying to find schematics for the samson 120 servo amplifier. where can i find them. I need to trouble shoot the protection circuit.

Hi, maybe your audio source is providing signal on left channel only, have you tried a different audio source?

Hi...try this...http://sportsbil.com/other/SAMSON%20SERVO%20170%20260%20550%20SCH.pdf thanks...hope it helps,

Have you checked the power supply section? Also look out for any IC's in the amp stages. They can go causing that kind of fault.

Fuses blow when there's an overload. Nine times out of ten this is caused by a short-circuited device on the heatsink.

You have lost a circuit. this is a problem that you can not fix yourself.

Check to see where the nearest "AUTHORIZED" service center is.

Do NOT take it to Joe Schmoe stereo repair!

Use ONLY an "AUTHORIZED" repair center!

Going anywhere else could result in YOU replacing your unit!

I dont have The diagram
Carlos sorry :O[
can you find the "Bridge" switch?

Hi...

This amp will need to be serviced

Check on the web for someone who does audio/stereo repair in your area

One of the channels in the amp is bad. That channel will need tobe replaced. You may need to take it to a repair shop.

my friend resistors and diodes don't just go off your circuit without a real problem. those parts gave up because of shortage on your power section, i suggest that you check your power transistros first along with the diodes and resistors.

noisy transformers... hmmmm why is that making sound? the solution there is to dip the power transformer to a thick shellac varnish let it there for let's say an hour then let it dry for a day. then place it back in your unit and see if still sounds
