Hi there,
I was recycling some old PCB and got a couple of TDA2030A chips. I want to build a stereo amplifier with them but I am missing some 220nF capacitors. In the circuit the C7 capacitor is 220nF. I couldn't find it in the nearest shop but I have some 100nF caps. Can I use 200nF instead of 220nF for C7?

The C7 should be a low inductance film type, and is critical for stability.
Two in parallel should work, but keep lead lengths short, and locate R44/C7 near the terminal #4.
