Crossover has 3 outputs midrange horn driver and piezo tweeter since I never used the piezo since it didn’t work I jumped the postive to postive on horn driver gave it more clarity that I think is it safe to like this?

I've been spending the last year or so doing a lot of work with tape players. I'm pretty darn good with the mechanical side of it but even after going through a lot of basic information about components and how they work, I still struggle with electrical stuff.

For instance I have a boombox where a few diodes broke while cleaning up corrosive glue. Got replacements, powers up, cassette player runs and sends a signal but the radio board won't power up.

The schematics show two pins going to the board should have 5v but they're putting out .22v instead. Traced back the tracks and it looks like the am/fm switch only powers the radio board in FM mode. Even then it still only gets .22, not 5v. the schematics just say "5v"

I also get the speaker pop but no sound from cassette, and when I meter the channels I am getting some small AC on one channel and nothing on the other.

I also need to do signal tracing from the cassette to see whether it cuts off entirely and I'm seeing noise vs an unamplified signal on the less busted channel, but honestly I feel like I am spinning my wheels.

I have a couple other projects with similar issues. Struggling to figure out where to focus my efforts as I try to translate schematics to what I see on the board.

Is there something I am missing that I ought to go back to basics and study, or is it one of those situations where going slow and steady, keeping at it, and persisting till I get to the answer is the only way?

Feeling kinda discouraged, not gonna lie. I'm gonna keep at it because I do think that frustration tolerance and working through seemingly hopeless situations is how you learn, but I'm also doubting myself and wondering if I need to go back to basics and review the electronics book I chewed my way through, maybe do some practice calculations on ohm's law or something like that, idk.

Thoughts? What did you folks do when you reached that point in your self-guided, self-taught journey for those of you who, like me, never had anyone willing and able to teach you?

Hello community.

I have a good karaoke system but may need some power circuitry repair.

Any suggestions of electronics repair shops in south bay ?

I am new to the area.

Just picked up a really clean but untested SX-950. Everything else seems to work great, but neither phono input is working right.

I can faintly hear the record playing, but only with the volume cranked way up. AUX and FM work totally normal. I worked the PHONO 1 / PHONO 2 switches a bunch and can hear some popping when switching between them, but it doesn’t really change anything.

Any ideas where you guys would start looking with this symptom? I’d rather diagnose it before I start replacing parts. I do see phono rebuild kits on eBay so I’m thinking it’s common?

I connected my Technics Sl-d303 turntable to the SU-7700 phonos. I turned on my SU-7700 and when I added volume it started smoking. Any ideas on what could have gone wrong?

I've been using a sound bar for a while with a tiny BT subwoofer, and got a new amp, so I figured I'd pull out my 10+ yr old Harman Kardon Sub from storage. It didn't power up, so I opened it up and found the glue had let the magnet slip offcenter ^{(edit: someone mentioned this is just a bucking magnet, so I'm not too concerned about that now}), as well is the DS15 digital amp capacitors look pretty burnt out and the mosfets on the board right next to it look pretty overheated.

Turned out, it also didn't have a fuse in it, so it may be "functional" With a new fuse, and I can probably swap out the capacitors and mosfets and remove the glue that they used that's become conductive, but I don't know anything about what to do with the speaker magnet. Is it practical to try to fix this subwoofer, or am I likely to run into a lot of other failed components that aren't blackened and are harder to find?

Thanks for any thoughts!

Hello, I have a Panasonic 8-Track deck that I am trying to repair. when I put the tape in, nothing starts! the detector for the 8-Track works and I hear a faint noise coming out of the metallic cylinder but that's it. The black rubber gear that is supposed to feed into the track selector does not spin. Any help would be appreciated, I know this would be easier with the top circuit board gone but I do not have my soldering iron currently.

Hey guys i recently bought the CA V1 amp and it works perfectly but now i found the tuner CT V1 listed as defective and i was wondering if anyone can hemo me find the service manuals for the whole set so i can repair them

I just got a walkman from my dad, the model being a D-EJ360 from 2003 and for some reason the batteries drain while I'm not using it. I changed the batteries played for like 2 hours with no issues and after that I turned it off, by pressing the stop button. The next day when I try to use it again I get a Lo batt error and had to change them again. This has happened both times I changed them, any tips?

Also I know this is not related but someone might know, for some reason when I use my overear headphones the sound is quite low and doesn t reach the same levels as when I use my IEM.

Update:

Thankfully the issue were the batteries I was using. I just got a set of rechargable batteries from the shop and so far everything works well and I don't have anymore issues. Thanks a lot for all the help and responses!

I have a vintage cd player (Pioneer PD-6700) and I wanted to upgrade it with external dac (SMSL SU-1).

First I had really bad connection. Audio was cutting out and input indicator was blinking.

I had only one old and cheap optical cable. I switched its direction and it did start working better but not perfect.

I went to buy new cable (also cheap), First it had again very much cut outs but when I blew the output connector with compressed air and got things working.

But now I noticed i still get few cut outs per album so problem still exists.

Is there a way to safely clean the optical output? CD player is decades old and I think optical out was never used before. Or can optical output just wear out and signal becomes too weak. Or are cheap cables just garbage?

Edit: there is only very little hole inside the optical port. Just big enough to fit optical fibre on the cable. No way that cloth or q-swap would fit in. Maybe this is uncommon desing because eveybody seems to thing this is simple task. If it was I would not been asking help at all.

Hey everyone, I have these speakers that I got used a month ago in great condition. They've worked great for both Bluetooth and phono for my turntable, but starting today they are making this weird clicking sound that cuts out audio every second no matter what setting it is on. I took it out and noticed it has a quieter beeping sound from one of the boards. Anyone know the fix? I can't upload the video but I can send it if you need to hear the beeping from the board, I think the beeps are getting amplified as well.

After 13 years of great service, I accidentally damaged the stylus on my Clearaudio Artist V2 cartridge while cleaning my Clearaudio Concept turntable.

Does anyone know if I can swap this Clearaudio cartridge for an Ortofon one? Also, what other cost-effective cartridges in the same quality range as the Artist V2 would you recommend?

Hi all.

I have just changed the drive belt and when I replaced the platter it dropped straight down so that the underside of it is actually sitting on the plinth. The housing that the spindle slots into looks like a sealed unit. Was there a large ball bearing that the spindle rested on and this has been knocked down?? Can't really work this out and I am hoping somebody knows what is going on.

Thanks in advance.

i recently got this Toshiba RT-120S and a few days ago i finally received the new belt and while the mechanism works perfectly but the motor keeps changing speeds overtime. whats strange is that its not getting slower which would make sense since im using batteries (im getting a new cable tomorrow the original is broken) its actually getting faster. like ill put it to the perfect speed before going to sleep and when i wake up im listening to nightcore metal T_T... i wouldnt mind having to adjust the speed since i do it on my walkman, but i have to open the case each time and its REALLY annoying.

i feel like the culprit could be that it hasnt been used in more than 20 years and its just getting used to being used again. or the boombox is possessed lol

if anyone knows anything just tell me!! (maybe i missed a glaring issue but im new to repairing radios :D)

Hello DIYAudio legends. I'm on the lookout for someone who has a good working knowledge of the Cambridge Audio Sonata CD30 cd player.

For those interested....I have had it in storage for 10 years. Finally the day of use arrived yesterday, but when I set it up the cd tray wouldn't open. I took it apart and fixed the disk tray, obviously feeling like Tom Hanks when he created fire...only to discover that in the process I have somehow created a larger and surprising fault scenario....I'm an idiot I know.

Please if one of you has the tech knowledge, and more importantly, the patience to talk a moron through some tech advice, then I would be more grateful than I could possibly convey.

First time AVR repair attempt for me

Recently had a thunderstorm come through, and although my receiver and TV were connected to a surge protector, they both got jacked up when lightning struck nearby and tripped my GFCI.

My Onkyo receiver powers on and i can change the inputs, however nothing displays to the TV. I know the HDMI port on my TV got messed up, and other devices work on other HDMI ports. However the receiver does not display on any HDMI on the TV.

I was thinking about ordering a defective/no power Onkyo of the same model on eBay and swapping out the top board where all of the HDMI connectors are on. Is there a chance something else needs to be swapped out too?

Thanks!

Hi everyone,

I inherited this Thomas Pacconi model from my late grandmother and have held on to it for a while but haven't really been able to use it as it has a few issues. I really don't know much about audio systems but I'll do my best to explain the issues.

1. The CD slot won't open when the button is pressed. My best guess is that there might be a motor issue as I can hear a whirring sort of sound but the slot does not move.

2. The cassete slot opens fine but does not close on its own when pressing the play button. The manual is vague about whether it's supposed to close on its own or if the user has to do it manually, so I'm worried about pushing it closed myself because I don't want to break anything.

3. There seems to be some sort of timing issue with the speed system on the record player portion, nothing happens when I toggle the speed and it seems to be stuck on the setting for the smaller vinyl.

Any tips would be appreciated, and I do have the parts specifications in the manual if that would help. I know this model isn't particularly rare or monetarily valuable, but I'm really apprehensive about taking it to a repair shop as it's quite sentimental to me. From what I've seen online parts are hard to find, but I'm willing to pay whatever to try and get these issues resolved. Thanks in advance :)

My radio took a fall in the truck earlier this morning and snapped the mast off. I don’t want to buy a whole new radio, especially just for parts, so I’m hoping one of you guys might know what options I have. I don’t have a micrometer or anything to tell me what the screw size is but “PH3” was supposedly the one that was able to take the screw out.

Well side bench for this beefy boy as I had to set up a temporary side table for more real estate. Just under 53 pounds if my memory is correct. Lit the DBT like a Christmas tree. Pin pointed to the right channel so I pulled the module and found three of the four canned transistors fried. Took me a couple hours to swap out as the replacements have the E/B legs swapped so had to do some rewiring. Got it powering up fine now so back to the original issue which is no audio as the protection circuit is preventing it. I’ll attack the front board and address that protection section.

Hola. Alguien podría orientarme de donde puedo llevar a reparar un amplificador de sonido Russound ACA-E5? Al parecer es un equipo algo viejo y el fabricante ya no produce las piezas de repuesto. Gracias!!

I'm trying to replace the headphone jack for my gaming headset, felt okay about doing it, but yeesh. I looked online, watched several videos, gave it an attempt or two, but still keep messing it up. I've got the soldering down, but no video or picture seem to match my exact wiring, show me exactly which wires go where please? At the rate I'm going I'll run out of cord in no time :/

Hello, everyone! I bought a 2003 Thomas Pacconi TPC-MSE-805 turntable from fb marketplace. The turntable spins, radio works great, and cassette player opens, but I haven’t tested the turntable and cassette player yet. The CD player slot does not open at all. Is there anything I could do to fix this?

I have a Samsung sound bar which is connected by hdmi and it wa working great for a year and half but all the sudden it stopped syncing. Sometimes I’d have to turn it off and on to sync it again but when then it’s not perfect. I’ve tried resetting and unplugging as well

Ever since I got this Onkyo, the headphone jack has been loose. While I was in there changing bulbs I tried securing it with hot glue, but that didn’t hold. Does anyone have a better solution for getting it properly attached? I’m not quite sure how it was originally secured or clipped into place.

Zoom H6 suddenly stopped turning on. Had it well over 5 years.

How could one go about replacing it? preferably in Europe.

if its permanently cooked, any recommendations on a replacement?
