Looking for TDA 2050 circuit boards
 
Anyone know where one can buy or order a decent circuit board for the TDA 2050 chip? I have 25 of these chips.
I've been searching and I have found numerous pictures of designs but no boards except for elliot sound products and 15 bucks a board plus shipping to Ohio USA is more then I would like to spend.

I bought 2 assembled TDA 2030 2.1 amps off ebay and they sound nice but you can only use a 12 volt supply which drops the power down.

Thanks,

They are compatible with LM1875 and TDA2030 or 2040 , that should help you broaden options.
I suggested a stereo one in an LM1875 thread.
Search for it.

i'm now using an amplifier with these pcbs and work really well with a supply of 18 - 0 - 18 ~ and in continous 25 0 25

You can use LM1875 boards for TDA2050. Pin out is identical and so are supply voltages etc. Gain for the TDA2050 must not be lower than x 16 ! Most boards show a gain of around x 33.

Thanks I will begin the search for LM1875 boards.
It would be quicker if I sat down and learned a PCB program but I have very little patience for PC programs.

Since the TDA2030/2040/2050 and lm1875 are only 5 pin chips the pcb"s are really easy to design , you can probably design one in about 30 min and have a home etched board a hour later .......

Cheers

You may even open this factory suggested PCB in any graphics program, resize it so it prints to proper scale (so parts and specially the IC fit) and then print it on regular paper with any printer.
Then you put a piece of transparent/tracing paper and hand trace it with a black ink pen.
Presto! You have a 1:1 PCB artwork.
You can even draw it straight on copper with some water resistant "Sharpie" pen.
Google "handmade PCB" or search You Tube.
Depending on technique you might have to mirror the drawing or not.

I found some boards. I'm not ready to start making my own PCB's, if I knew more I would attempt it.

Jsixis- what boards did you find? Could you kindly post a link?

Got an email from Deep Singh email is audioampdiy@gmail.com.
I found him reading some older posts on here.
