Apparently Hartke and Samson are one and the same. See if possibly this link might be close to your unit. It is for an S500.

SOURCE: I have a Samson Servo 300 2channel audio

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Finally probing using a multimeter to check for short in circuit is only a preliminary step. Since there are densely packed board it is beyond a certain limitiation to check on component level fault as the board replacement will give a faster result to converge on the section.

I bought a 3.15A/250V- 220 V for my servo 240 and it keeps on blowin everytime i put on a new one.


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

My samson servo 300's sound keeps cutting out, want to spray some electronic cleaner but not sure where ?


Yes; It maybe the protection coming on and off. This means there is a short in a speaker wire , or a blown speaker. The amp has 2 options for speaker hook up.1/4" plug and direct wire. If you are using direct wire it is possible to have frayed ends hanging around and can cause a short. You can test the speakers by unplugging them at the speaker, before you turn on the amp. Then turn it on, if the clicking still persist's turn off the amp and disconnect the speaker wires from the amp . Turn the amp back on. If the clicking still persists there is an internal problem with the amp. If not then you defiantly have either a wiring or speaker problem . You can test the speakers by using a 9v battery . Hook up the speaker wire to the speaker and put the battery on the other end of the wire, you should hear the speaker pop and see it move.If it moves it is still good. Note* this is also a good method of making sure your speakers are in phase. The battery is marked + & - the speaker will move forward when + is applied to the + of the speaker. make note of which wire is the +. if you get one speaker backwards it will cancel the sound of the bass. so hook the + to the red on the amp. Hope this helps you

Hi, i have been suggested first a Samson servo 600, then a sx1200 is there a difference between the 2? is one better than the other?


the servo series is geared more towards studio applications and/or installs, while the sx series are geared for live pa applications. the servo 600 is 300 watts per channel @ 4 ohm, and the sx1200 is 450 watts per channel at 4 ohms. the sx amp can also be bridged over to mono mode, where it puts out, i think, 1100 watts mono.

the only variable i havent been able to cover is sound quality, and im not seeing those listings in the specs on the samson website

No sound coming with protection light on


It's either overheated or you may have faulty speaker wiring or a shorted speaker. These directions come from a Samson servo 120a but the theory is the same.

The following conditions will cause the Protection LED to go on:

Initial power-up: For approximately five seconds after initial power-up, the relay

speaker connection circuitry is deactivated and the speaker output is muted. If everything is operating normally, you will hear an audible click at the conclusion of this brief period, as the circuitry is activated and the Servo 120a begins delivering signal to connected speakers (at which point the Speaker LED will light if the Speaker on/off switch is in its "in" position). It is normal for the Protection LED to fade gradually after the amplifier is powered off.

Overheating: A temperature sensing device in the Servo 120a will cause the relay speaker connection circuitry to be activated (and the Protection LED to go on) whenever the operating temperature of the unit rises above a safe level. To guard against this problem, make sure the Servo 120a receives adequate ventilation on all sides ; in extreme environmental conditions, you may also

want to consider the use of cooling fans.

Severe overcurrent conditions: This occurs whenever the signal being output

from the Servo 120a rises to a level above 20% THD (Total Harmonic Distortion).

Shorted speaker cables: This will occur if, due to faulty wiring, the hot and ground signals being output by the Servo 120a short to one another.

Output impedance drops below 2 ohms: This can occur if the Servo 120a is connected to inappropriate speaker systems (see the "Setting Up and Using the Servo 120a" section in this manual for more information).

DC voltage detected at speaker output: The most likely cause of this is an internal failure. In general, any time the Protection LED lights up (other than during the approximately five seconds following initial power-up), there is reason to be concerned. If this occurs, turn the Servo 120a off immediately and carefully check all wiring and external devices in order to locate and correct the condition that caused the LED to light up in the first place.

Samson Servo 170 protection circuit problem!


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
