Re: amp power

Scottymac and to all. Power transformer for power amplifier are high current. resistance on both primary and sec are surely very low, one can think its shorted. If all fuse and breaker are OK surely it will fire up or at least show some indication that power is present...lamp or led display for the power, clip and protect (basically)...provided that the SWITCH is also functional. Switch, fuse, Volt selector and the transformer primary is just about what makes the whole circuit to fire your transformer. If all of this components are OK, it should and surely will fire up...But what about if the transformer being switch on by a TRIAC (Thyristor) found in most new AMP today? Make a double check. Hope this will help. Good Luck.

Re: amp power

Question on the Transformer resistance measurement. If the secondary windings output without load only shows less than 1 ohm but the voltage across the 2 output wires is about 15V, is this Transformer still OK? Is this normal that the Transformer output impedance or resistance number that very low?

Re: amp power

Make shure with an ohm meter that the primary and secondary windings have very little resistance on the main trasformer,then check voltage in trasformer and out from transformer...BIGRED

Samson SX1200 - Protect light on. No blown output transistors.

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.

I have a s1500 samson amp I keep blowing speakers, what can I do to prevent this from happing again? The speakers that blown first was two 12'' yorkville 350 w impedance 8 ohm, the next speakers that blown...

Turn the volume down? Feed it cleaner source material?

You don't say under what conditions you're blowing them or if any of the informative indicators are warning you of impending doom. The Samson is capable of cooking just about any home speaker.

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

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

protection circuitry is activated 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 protection circuitry is deactivated and the S1500 / S2000 begins

delivering signal to connected speakers (at which point you'll hear a click). It is

normal for the Protection LED to fade gradually after the amplifier is powered off.

Overheating: A temperature sensing device in the S1500 / S2000 will cause

the protection 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 S1500 / S2000 receives adequate

ventilation on all sides and that both the front and rear panels are unobstructed.

Severe overcurrent conditions: This occurs whenever the signal being input to

the S1500 / S2000 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 S1500 / S2000 short one another.

Output impedance drops below 2 ohms: This can occur if the S1500 / S2000

is connected to inappropriate speaker systems (see the "Setting Up and Using

Your S1500 / S2000" section on page 5 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 S1500 / S2000 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.

For further assistance, contact your local Samson dealer. If purchased in the

United States, you can call Samson Technical Support (1-800-372-6766)
between 9 AM and 5 PM EST.

Fuses keep blowing on my Samson Servo 120a

If after putting in the right rating of fuse you have a blow out, then you must diconnect the speakers and test. If the fuse hold ok then the speakers must be checked for shorting or fault in the network. However if the fuse still blows off, then you will need to take out the cover to test within the main board for the power section or output section malfunctioning. First of all discconnect the power to the output stages and test, if fuses blows check the powersuppy section, the rectifier to the main capacitors for reduced values. If not check on the output stages, the drivers, the predrivers for malfunctioning. However you will need some knowledge of electronics to probe stage by stage to isolate the fault.If not get help to proceed. Good day

Need fuses for samson amp

The manual recommends 4 Amp Slow blow for 115 volt operation or 2 Amp Slow blow for 230 Volt operation for the 201a.

For the 260 Amp manual shows 10 Amp normal for 115 volt operation and 5 Amp nomal for 230 volt operation.

Used banana plugs for my amplifier, but bare ends of cable were too long, and then my amplifier short circuited. Silly. I would like to know if the IC is toasted or the power supply (or both). Is this...

If you were playing with the speaker out ----off sure the amp IC is blown or the related circute problem as occured
if you smell the shot circute ...tipically a silicon burn smell....then ...there is a problem in side....
remove the cover and physical check for the blown parts using a tourch if you fing any parts or the bord blackning.........
fault may be there\
some times with a small blown fuse replasement ...cure's it .........
