Putzeys demo preamp Vol 5 power Rs

In Volume 5, Bruno Putzeys offered a demo preamp project as part of his article The G-word, or how to get your Audio off the Ground. In the power supply section are four 2.2 ohms resistors, R25, R26, R27 and R28, as inrush limiters. The ressitors shown in the BoM however are not themselves inrush-resistant. The correct resistor type here is VISHAY BEYSCHLAG - MMA02040C2208FB300 - RES, MELF, 2R2, 1%, 250MW, SMD.
