Hello mate.
If you have a linear source with transformer check that the primary winding is not shorted, it can become the rectifying punch of the output. If the source is switched normally it is the diode bridge, the main filter capacitor and may the transistor switch. It may become the AC input,
Regards!

Best regards, friend Merardo, if the equipment is flying the fuse should be cause of a short circuit and you have to check where this short is, if you know of electronica and you have the appropriate tools, you have to check it from the power transformer if it has, followed by rectification and power source and everything related to this as they are regulators, diodes, transistors, if you discard the source is the reason of the short you have to go to the amplifier stage and check the output transistors that at being short may cause the fuse to open, I recommend to check first before placing another fuse again as there may be more damage if you are putting the fuses without knowing where the short is, remember to comment your results to continue in your support . regards

Hi, I followed the indicated suggestion, disconnect stages, source, preamplifier, amplifier, protections, etc, most likely the source if it is smps or output amplifiers, those stages consume a lot of current and can cause serious malfunctions. Disconnect power from the circuit integrated output or transistor manifold if discrete, and measures voltage source. always try everything with a series lamp.
