OEM Boards?

unclebuck · 18th July 2010, 11:30 AM

Thought I would ask you guys here at DIYaudio.

If you are interested in buying a class d amplifier board, there are thousands of boards to buy from all over the world. But if you need a preamp board to match your class d amp there not more than a handful.

I need boards for:

-MIC preamp (bal/unbal) (cost no more than 80 dollars)
-EQ (cost around 40 dollars)

Ideally would be a MIC preamp with tone controllers built in from the start.

Been searching the internet for months but can´t really find what I´m looking for. The cheapest/most value for money, would probably be to buy a Behringer 100 mic/tube pre for 40 bucks and tear it apart. It lacks tone controls though..

Any valuable link to an asian OEM manufacturer or american company that sells micpreamp boards would be much appreciated!!!

I'm not sure if you mean boards that are already functioning or blank pcbs. Vikash has some nice Walin Preamp boards Mad About Sound | Microphone Preamplifier PCB v1.1

No tone controls but works nicely for me. I have a revision 1.0 board
