TDA1074 as quad pot

Dxvideo · 28th May 2005, 12:10 PM

Hi all,

I wanna build a 4+1 with 6 x LM 1876. My gainclones are ready to install but I cannot find a quad tandem pot in Turkey. So I planned to use TDA1074A instead of quad pot.

Does anyone use TDA1074A in a volume control circuit? Or anyone has any information about TDA1074A applications?

Thanks in advance for your assitance.
