    Yamaha ns700x crossover high frequency section capacitor parameters

    Please help me find the nominal values of the capacitors in the HF section of the Yamaha ns700x crossovers. I decided to check the capacitances in the crossovers of the acoustic systems, and there are aluminum cylinders on the HF, without any distinguishing marks. I can't find any technical...

    Doubt changes with age aluminum electrolytic capacitor

    A used aluminum electrolytic capacitor manufactured in the early 90s and mounted on a PCB. Is the dielectric, electrolytic and chemical composition altered by age and use compared to a new aluminum electrolytic capacitor manufactured recently? If there is this difference between them, then...

    Aluminum electrolytic capacitors storage

    aluminum electrolytic capacitors stored because manufacturers recommend energizing them before 2 years of storage? Is this rule only for new, unused aluminum electrolytic capacitors? Is this rule not useful for aluminum electrolytic capacitors manufactured in the early 90s and mounted in...

    Capacitor between XLR shell and ground pin

    The topic isn't new, but still seems to be contested. Here and here it is advised to add 100pF capacitor in a way that both pin #1 and shell are connected. Is this what's normally recommended or connection between the cable and pin should be severed? Also, what is the optimal capacitor...

    Capacitor upgrade in crossover - Is it audible? - Part 2

    Here is the second part on the topic "Capacitor upgrade in crossover - Is it audible? This time it is exclusively about the measurable differences of electrolytic capacitors with film capacitors in crossovers of loudspeakers. The first part about film capacitors can be found here and who likes...

    Capacitor upgrade in crossover - Is it audible?

    As the topics "capacitor upgrade" and therefore "capacitor sound" is very controversial, the test method and its results are explained in detail. This cannot be dealt with in one minute. Sorry for this and I hope your attention span is still sufficient to read through a long text - whereby the...
