My Ref"C" PCB's

Would like to find a set of Twisted Pear Boards for the Ref C chip amp. Also would like to have copy of the schematic. I know there is a set of boards out there that hungers to be in Arizona!!

Thanks..

Have you contacted Twisted Pear?

sandyhooker · 1st July 2009, 06:15 PM

I checked their website and the item is not listed.I suppose an email is in order. I'm surprised that there are'nt more boards available for the LM3886 chip. Most use the original National Semi data sheet schematic which has some short comings.

Twisted Pear will give you the artwork to make your own, it used to be on their site but it's gone now I think. You can try posting in the tradin post.

Best, Bill

If you search for a pcb with LM3886 you have plenty out there, a dozen at least including mine.

Thankyou very much..I am really not set up for PCB fab. I did it years ago with the Kepro negative system but ,now, would rather not get involved.Am thinking about going to the TDA 7293/94 as boards are available.

If someone had a set of boards utilizing a decent circuit I'd stay with the LM3886.

Thanks for your reply...

As peranders said, a search will find you some. If you're looking for single chip per channel setups, two that come to mind right away are:
