My pioneer receiver SX828 will blow the fuse on the rear of the unit 3A-125volt. as soon as i turn it on > it turns on for about a second then the fuse blows!!   there is no burnt smells from inside. it is very clean and dust free inside. i know these older receivers run hot, but there is no odors that tell me that something has overheated or blown.  (to the best of my knowledge) !!  i know this is a very technical question and lots of things to check but i thought i would ask !! thanks, brian.... bksierra62@yahoo.com

I have an 70's style turntable/radio console.?

I have a Magnavox 591558.  The issue is that the audio from the turntable is diminished out the left speakers. The FM tuner works and sounds great, however when using the turntable, left audio is very muffled.  As a troubleshooting step, I hooked up a Stanton STR8-100 turntable, with pre-amp, as a replacement to the built in turntable, and get the same results.  Good audio out the right channel, but muffled out the left.  So I know the issue has to be somewhere on the circuit board, as the Radio is fine through both channels. I do not see any blown capacitors, or any sign of damage on the circuit boards.  I'm hoping someone here can point me in the right direction.

How do I fix my car stereo ground wire? Answered

I installed my new stereo and it won't work. The fix-it hotline told me to touch the ground wire to the negative batt. terminal, and the red and yellow wires to the positive terminal. The stereo worked, meaning the ground wire coming from the dash is probably bad.?

Hook up stereo speakers to computer for surround sound

Alright, if theres already an instructable on this, I apologize, and could someone point me to it, otherwise, here's my question: I have a set of stereo speakers, the ones with the clips that you use to hold in the wire, so it has no plug. The only stereo set I have has no outputs, no white and red RCA jacks, or anything, and I do not have any other reciever. Is there any sort of adapter I could buy or build cheap (easily, preferably) to let me plug two of those into a standard 3.5 mm miniplug? my goal is to use those as rear speakers for my computer's 5.1 surround, as they have good base and treble, and my 2.1 channel set that I was using there crapped out.

Home stereo stopped working possibly has burnt out voltage regulator? Answered

Greetings, My Altec Lansing home stereo stopped giving out sound.  There is still fuzz audible from the speakers, but there is no musical sound whatsoever coming through the speakers.  It is a simple stereo but with good sound.  It has one input Jack which has always been loose and finicky; as long as I carefully plug into the Jack and make sure it is a good connection, the stereo has worked fine.  One day however it suddenly stopped giving any musical sound.  I decided to open up the stereo and look inside.  First I tried bypassing the input Jack since I suspected that was the problem.  Bypassing the input jack however made no difference, there was still zero audio signal coming out of the speakers (still only the buzz).  I then looked around on the motherboard to check for any oddities. Everything looked normal except for one Voltage Regulator.  It is a L7809CV.  It has three prongs and a built in heatsink. The point at which it connects to the motherboard is slightly burnt looking as it is discoloured. In the upclose picture you can see two voltage regulators, the one on the left is the one which appears burnt. I was thinking this is likely the culprit.  Would anyone on the forum have any feedback to offer.  Do you think this is the problem, and would replacing the voltage Regulator likely fix the amp?

Building custom tiny stereo to output sound from two different sources

Hello there, I'd want to build a tiny custom stereo, small enough to be mounted on a forearm. It has to receive input from two different sources: my smartphone (should act as a simple mp3 player) and a head mounted microphone. As I'm not into electronics really, I would use some help. I've read this instructable as reference: https://www.instructables.com/id/Simple-Stereo-Amplifier/ I'm not pretty sure about what kind of speakers I should use and what exact components I should need. I'd want to use two speakers and I don't really care about stereo sound, actually I would prefer mono sound. Maybe I could use one speaker for the phone output and the other one for the microphone output. I'd also like to put the amplifier distant from the speakers, since the forearm mount should be as slim as possible, so I'd put it in the back trousers pocket, if I manage to make it small enough. As you see I'm kind of confused, I have ideas, but not knowledge. Have you got any guide or whatever I could use? Thank you for your help!

Car Stereo Antenna for In-Home use? Answered

I'm decent with working with modifying electronics, but I don't have much experience with antennae, reception, or any of that good stuff. I have plenty of experience with soldering, both wire connections, and motherboard components, so that's not a problem.. I already have my stereo wired to my computer's psu, with the pci-e power, and already have everything hooked up as of a year ago.. Aux In, Usb, and Sd all work fine, but I can't use the FM radio function, due to my lack of an antenna.. I've heard of bending a coat hanger, and shoving it in, and I don't like that shotty work, and I used to have an extension, or an adapter, (Not sure exactly what it was), but It got mediocre reception, and I gave it to a friend that I hooked up a stereo indoors for.. I can find such an adapter cheap, but I want something that will get AWESOME signal.. I know most components that require lengths of wire drop voltage, or signal over distance, such as power cables, Cat5 cables, so on and so forth.. So what can I use, modify, or make to get the reception I want, on a budget? I don't want a crappy fix.. I just want something affordable, reliable, and something that won't look too horrible. I have the stereo mounted to my desk, so not much will be exposed, depending on the length of said antenna, Thanks in advance!!

Circuit to connect stereo output to 5.1 speaker system?

Hi all! I am after a circuit that will mix a stereo source together (into mono) then pipe it out to a 5.1 speaker system. Obviously the simple solution is to wire the left and rights together and then patch into each speaker on the 5.1 speaker system. However it causes noise and other audio artifacts. I am thinking some form of op-amp type circuit to mix the L and R. That then either can be directly split between the speakers or goes into another pre-amp circuit for each speaker output (maybe even a band-pass for the sub woofer). Just to explain what this is for: I want to have music in a workshop. At the moment we have a standard radio which, to be heard the other side of the 'shop, is quite loud. Those near it then turn it down and arguments start (not quite but you get the idea!). I want to use my old 5.1 computer speaker system to spread the sound around the 'shop evenly so the volume is constant no matter where you are - a poor mans PA system.
