| These MFR5 resistors are metal film type (high stability, low noise) and rated at 0.75 Watts (heat dissipation) and will withstand up to 350 volts. They are also physically small (3.2mm diameter x 10mm long) and accurate (+/- 1%) with a temperature coefficient (value drift) of only 100ppm per degree C change in temperature. Tinned copper wires are 0.8mm diameter and approx. 21mm long. They are so versatile that they can be used in audiophile applications, valve and transistor circuits and in high voltage power supplies. If you are in any doubt, this is the resistor to choose! Sold individually at 69p each but with automatic discounts for quantity (breaks at 10, 100, 500). Audiophile? These are NOT so-called "Audiophile" resistors. I advocate them for audio use for one simple reason: they have a low temperature coefficient, which makes them very stable. The metal film means that they generate minimal electrical noise. In addition, they are rated at 350 volts, which means that they can be used in valve circuits without any fear of breakdown or reliability problems. Whether you'll hear any difference is down to your ears and I'm not going to make any unsubstantiated claims. For audiophile use I recommend using lead-tin solder simply because it flows well and produces a smooth, shiny joint. If you insist on using lead-free solder, I recommend the type that includes silver - not because it costs more, or has any magical audio properties, but because it flows better.
