How to prevent an amplifier fuse from blowing?
The simple amplifier fuse protection circuits presented here can be effectively used for solving the issue. The problem is commonly seen in high power amplifiers, where the loudspeakers have low resistance specs, or in power amplifiers which have many high power loudspeakers connected in parallel.
What’s the correct amperage fuse for my PC?
If you are talking about the power lead itself (IEC Lead) then a standard 5A sounds about right for a PC. Based on your input power of 200-240V 4A (in UK) You must remember that the fuse in the plugtop is there to protect the cable and not the PC.
Why does my amplifier burn during power switch on?
The situation is undesirable not only for the amplifier, but it may be also a threat to the loudspeakers, which may eventually burn due to repetitive high current switching, during every power switch ON. The idea is actually quite simple.
What to do if there is no power to an outlet?
If a blown fuse is the culprit, unscrew it and replace it with one of the same amperage. A loose wire inside of your box or an outdated electrical panel could very well be your holdup, which would require the help of an electrician to troubleshoot; however, we have one more thing you can check before calling for professional assistance.

What causes an amp to stop powering up?
This is a grounded collector Amp. The two large caps form a center tap for the power supply which is connected to the speaker terminal. So This is cap coupled amp. Therefore if you drive high currents of low frequencies the large caps will fail…it is a very graceful failure. The signal will just fade away.
Where is the fuse on an audio amplifier?
I have an audio amplifier (FPL 400) which constantly blow its fuse when started. I reproduce it even without speaker connected or audio input source. The fuse is located just after the power supply cable.
What does no power mean on a circuit breaker?
No power at the connection terminal while the circuit breaker is in the On position indicates a defective circuit breaker. Remove the receptacle cover from the outlet without power. Check for voltage at the wire connection terminals on the side of the receptacle. Verify the voltage is correct.
