Re: TEK 475: Dead on Start Up.

I don’t fully agree with that recommendation, although it is fine in many circumstances. The impedance of tants stays low at high freqs, while aluminums generally don’t. Tripling the capacitance doesn’t necessarily reduce the impedance. Above self-resonance the impedance is dominated by parasitics, not the capacitive reactance.

If Changing to electrolytic, triple the value… 22 uF/20Volt tant -> 100uF/25, 35, or 50Volt electrolytic
