    Gemsound PAX-105 Audio Amp blowing fuses

    Hi. New to this side of the forum.

    Have an audio amp (Gemsound PXA-105) that keeps blowing the 3A fuses upon power up. Owner stated that the amp was on when he plugged in the input (mixer board) and that started this chaos.

    Would a schematic be available? Advice on what to check? Power supply / output amp transistors? Do see the power on green led turn on for a brief moment before the fuse blows.

    Thanks.

      Schematic Digital Audio mixer RCF type M18
      by Bektronics
      Hello dear audio friends.

      I am feverishly looking for the full electronic schematic (not a block diagram) of the RCF type M18 digital audio mixer.
      The device does not make a WIFI connection with my Apple tablet and yet I have already installed the recent app on it.
      I suspect that there is a problem in the mixer itself with the WIFI card and of course I would like to see this on an extensive schedule before opening the device.
      Thanks in advance if anyone can help me with this schematic.
      Of course, all information about this digital mixer and possibly references...

      Help troubleshooting an audio problem with an RCA SGT-250 CED Player
      by samson7point1@yahoo.com
      The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

      The player processes the audio signal using two different reference frequencies. The "R"...

      How an incandescent light and a ESR meter ** friend**have a machine blowing fuses
      by sam_sam_sam
      About a month ago we had a transformer jumper wire that burned in two different places between two transformers caused over $200 thousand dollars worth of damage to VFD drives at least 10 of them and a memory card and quite a few power supply as well

      Now we have most of the equipment that got damaged back up and running except a feeder that has issues and we are waiting for some parts for

      Now we also have another piece of equipment that was blowing fuses on the 110 volt controller switch circuit with the “E” stops and one switching power (24 volt) supply and a transformer...

      HH Scott Model A510 Stereo Integrated Amplifier/ Graphic EQ - Blowing fuses in the LEFT speaker channel only. Any Help???
      by Sik_6ty_Sixx
      So like the title says, I have an old Stereo Receiver/Amplifier that I picked up from the goodwill, it's a HH Scott Model A510. When I first got it home it had zero output. Opened it up, notice the fuses are missing. Pop in 2 new fuses (AGC4A 250V) and try again, within 5 seconds the L channel fuse POP! I don't see any visible indications of damage or arc burns on the PCB, no popped resistors or diodes, no burnt traces or blown out caps. So I decide to just try another new fuse, POP. Swapped around my R and L speaker wires, and checked the integrity of all wires and connections. Everything looks...
