网上可用此计算器，    http://www.kabusa.com/riaa.htm
输入RIAA 补偿网络的R1 值，便可求出其他电阻，电容值。
开心享用。

计算完畢后須再诚回前一级的内阻，及750μS电容又须诚去受米勒电容影响的容量。

Hiraga (RIAA)

Schematic by Jean Hiraga and published in L'Audiophile n° 21 (Sept. 81).
Preamplifier

The resistor (220-1K) adjusts the response over 15kHz.
Power Supply

The original power supply, heavily filtered. I've increased the values of the capacitors.
