Are you talking about a transformer or a power supply? Transformers just change the value of AC e.g. 120 volts AC in to 12 volts AC out. Post a picture. Is it a complete module, marked with a DC output? They are very generic and can be had for a few bucks. How do you even know that is where your problem is? If the radio is just a 12 volt car radio try running it off a car battery to see if it works. Did you even try measuring the output of the supply module if that is what it is. Some Chinese in house part number is not likely to show up in a seach. This is not rocket science. Either the radio or the supply is bad. People run car radios off cheap little power supplies all the time. Stuff like this gets fixed with a little, simple trouble shooting, rarely with phone calls to a bunch of jerks that could care less. Let's see a couple of pictures of the radio and whatever else you have there.OK, called Cust. support. Nightmare..they referred me to pioneer, pioneer said they don't service the power supply, call Kobalt.. Then Kobalt referred me to Shanghai, the manufacturer of the box. Dead end...Leave a voicemail.
So I found the access panel. Very top shelf right hand side. 110 AC enter the transformer and no DC output. Removed the transformer and the protective shield to see a circuit breaker buts is OK. Trans. is an HTs-60F-12 transformer listing at an internet special of 251.99. NO...will be looking for a less expensive replacement after I call the local Lowes and share my experience.
Scratch part of my last post. That number was all over the place. Apparantly it is no longer available from that manufacturer but no problem. It is NOT a transformer, it is a complete 12 volt, 100 watt (8.5 amp) power supply. There is a virtually identical replacement on Amazon for $14.99. Look for GALYGG 12,volt power supply. You still need to see if it is the supply or the radio. You just need some garbage meter than can measure 12volts DC. You might even just have a bad power cord. If all this sounds too complicated, buy a radio but the fix might be a whole lot cheaper.OK, called Cust. support.

I don't want to muddy the waters for the OP, but the procedure you describe skips a step that may cost him a new head unit when he doesn't need one. He'll want to check that the head unit doesn't work when connected to a car battery or known good power supply, before replacing it. It's very possible for the power supply to have voltage, but not enough amperage to run the radio.Pull the radio out, with the unit plugged in to the wall, but the power unplugged from the head unit check voltage. If it's there, change the head unit. If there's no voltage, trace the wire supplying power to the power supply, pull that and replace it from something you have or a cheap one off eBay or Amazon. Make sure you get polarity right.

I've got a 20 amp supply on my bench right now that'll power a radio, but not much more. If I were to test, say, a window motor, with it in the way you describe, I might toss out a perfectly good motor, seeing that the power supply shows voltage on a meter.
Run the power supply number he gave. It is a lab type power supply module, designed to be installed in an enclosure,not some piece of plastic junk. Virtually all the capacitors in EVERYTHING are Chinese, though there is a definite range of quality. As the OP has not done the basic trouble shooting to isolate, the power supply, radio or wiring, it is premature to say he even needs a power supply. If he does not know a transformer from a DC power supply, it is improbable that he is going to be taking voltage readings or running the radio on a battery, etc. I do not say this to demean him as everybody has areas they are totally unfamiliar with I don't see this going anywhere unless he gets a little local help.I don't disagree but generally these cheap power supplies just die when the caps go because they always use those cheap chinese caps. It's probably not the safest assumption but I wanted to make it easy sounding as possible.
This thread really makes me want to hook up my old head unit to use in the garage or back porch but I have soo many BT radios...seems like a fun project though.

Yeah, guess they are. Alll the US brands like Cornell Dubellier, Aerovox and Mallory are gone. Also Pannasonic for Japan. The little supply I found looks like the one he thinks is bad and has identical specs but I don't think this is going anywhere.Japanese capacitors are in a lot of things, Japanese caps are the sign of a quality power supply. Nichicon, Sanyo and Nippon make great capacitors.

Sadly, people asking for help and getting many responses often disappear. We just had the guy looking for local help drilling large holes and getting several offers stopped responding. Not even a thank you.OP, where are you at on this? It looks like maybe you joined the forum specifically to get help with it, but you're not very responsive to your own thread. We can walk you through it, help us help you. We need to know if you have a multimeter, we need pics of whatever you can see, power supply, and back of the radio. If you see a model number on the radio, that would help. I'm curious of it's a regular automotive model. If so, there's definitely a fuse on the back of it, locked in and kinda hidden by the wiring harness (plug with power and speaker wires).
A higher wattage power supply does not make the radio play louder, it just means there is more available if needed. It is still 12 volts out. If the supply is rated for too close to what the radio needs, it is always running at full capacity and more likely to blow. Think of it like a 100 lb rated cable lifting 97 lbs. You are better off with a 200 lb rated cable. Considering that you blew one supply, a higher rated one was the logical choice, especially when the price difference was negligible. As far as guessing polarity, you are just lucky. That would have destroyed a lot of products. Pick up the HF freebie meter when there is a coupon or if you need one right away there are a few for under 10 bucks, that are good enough to check voltage and polarity. Again, it is not a transformer. It is a power supply which may contain a transormer. I'm glad it is fixed.Ok,I found an $11 transformer. Ordered it on Tuesday received it friday. The radio always did work but when I found the Power supply...power transformer.... in the top corner of the tool box, I replaced it and the radio works. Need to watch the polarity of the 12 volt side. I hooked it up (fifty fifty chance) and radio didn't work but didn't blow the 10 amp car breaker. switched around the black and yellow and PRESTO...the radio is working again. I considered getting the $14 dollar transformer to up the wattage from 40 to 100 but decided I would end up needing speakers ha. So we'll see how long this keeps the tunes in the barn going? Thanks for everyone's help.
