Vishay / Philips metal film resistors are considered among the best you can buy.
Metal film resistors are ultra low noise resistors and therefore superior for audio amplifier projects. Because of the low temperature coefficient compared to carbon resistor they are to be preferred for tube amplifiers.
|Resistor type||Metal film|
|Code||RN55E / MR55E|
|Temperature coefficient||25 ppm/°C|
|Applications||Critical parts in audio projects. In particular tube projects. Upgrading projects|
