Is it true that increasing the number of PSU Elcos can increase the power of a power amplifier?
•• Increasing the number of PSU elcos without increasing the transformer's volts and amperes is simply a waste, the number of elcos will not increase the amplifier's output power, because what determines the clipping point and the amplifier's power is the high PSU voltage and amperes, not the number of PSU elcos.
•• For example, the RDW FA23000 power supply uses a 155 VAC CT transformer with 20 4700UF 250V electrolytic capacitors. The calculation is the 155 CT transformer divided by the 4 ohm speaker load = 38.75 amperes with 4700UF electrolytic capacitors multiplied by 20 = 94,000UF, then 94,000UF divided by 38.75 amperes = 2,430 UF per ampere of the transformer, that's the correct calculation, and proof that the 20 4700UF electrolytic capacitors are only to adjust the capacity. The transformer isn't meant to increase the amplifier's power. What affects the amplifier's power and clipping point is the 155 VAC transformer voltage, not the number of electrolytic capacitors. Even if you add a sack of electrolytic capacitors, if the transformer voltage remains at 155 VAC, the output power will remain the same, and it won't increase.
•• So, when adding electrolytic capacitors to the PSU, adjust the transformer's voltage and amperage to a minimum of 2,000-3,000 UF per amp for proper function.
•• What's misunderstood by novice assemblers is that they copy the number of electrolytic capacitors in a built-up power supply and think they can increase the amplifier's power without increasing the transformer's voltage and amperage. That's one suggestion. For example, using a 10-amp 32 VAC transformer with 4 x 44,000 UF electrolytic capacitors suggests that the bass power will be very strong. 🤭 Where does that strength come from? The transformer voltage is still CT 32🤭 which actually makes your amplifier box heavier, the power output will be the same, that is one example of an incorrect calculation
