Hi all. I got a Dixon mixing amp and after doing the usual circuit tests, I found that the led driver ic is blown. I've searched all off the local components suppliers and came up with nothing. The ic is a Panasonic AN6884 5 DOT LED driver ic. Its equivalent in NTE1561, but neither I can get...

:facepalm: Hi there. Im in the middle of a DIY project. I repurpose any tech and other material to build practical, usefull and things you wont see everyday. So, my current project involves an old Blaupunkt turntable, a usb port and various other creature comforts. My usb port will be mp3...

:notworthy:Hi So, im busy with my latest DIY Repurposing project and i have hit a steel wall. Here is the setup so far:                               I have a Blaupunkt hifi turntable & cd player that some poor guy blew a hole into the amp circuit.                                   I have a...

So, i was reading a reply to one of my posts about how the guy wanted an under counter radio, and i replied to him with a hack i did a few years back. My sister likes music in the kitchen (busiest room in the house) so, i took apart an old head unit from a car. The space under the counter that...

undercounter, unobtrusive and fm is essential.............. Why not opt for taking a single din apart and enclosing it in a thinner diy casing. If its only for fm, then take the face away and hardwire power button and volume control to the main board. A few years back, i did a similar thing...

Hi again. I posted earlier that i wanted to hardwire aux input directly to the amplifier chip (TDA7454). I did it and added a switch to change between cd audio and aux audio. FYI, IM BUILDING A BOOMBOX WITH A ''VISTEON 6500 RDS SINGLE DIN CAR RADIO Anyway, it works wonderfully. But, me being...

Hello again. So i have a question about this little chip. I'm busy adding aux input to an old single din car radio. The best way, is to tap into the cd player's cable, but cd player does not read cds, so in turn, the aux sound dont come through. So i got the data sheet of tda7454 and found the...

So i got a Blaupunkt turntable hi-fi, but............it came to me without amp circuit. I searched for the amp ic by following model and serial number, but get results from Pioneer dvd players. (So its true when they say ''GOOGLE IS LIKE A LAZY EMPLOYEE- ASK HIM ONE THING, HE GIVES YOU ALL THE...

gatsonderend? More like dorpsonderlewe. Im in cape town, but im one of those tinkerballs that spen money only when its needed. This project is only not to throw away a perfectly good board. Besides, the audio output is very good. Later on, im planning to turn it into a portable media player...
