NOS Riken Carbon Film Resistors

Life of an audiophile is difficult. Life of an amplifier design is even MORE difficult. As we all know, a lot of the legendary vintage audio equipment are made with carbon composite or carbon film resistors, and that's one of the reason why they carry such a tonality that modern equipment do not have.  

We are building a batch of preamp for customers, and they specifically asked for NOS Riken Carbon Film resistors due the unique sound signature it carries. As we all know, carbon film or carbon composite resistors tend to drift in value over time due to temperature, humidity and run-in. Matching them is really pain in the a** and expensive task. We have to buy a huge batch of resistors just to match very few pairs.

Riken (Japan) RM2 2W NOS Carbon Film Audiophile Resistors
Tolerance: 5%
Size: 8mm D x 18mm L
Originality: Japan

Sound characteristics
* musical, warm, golden tonality, atmospheric, smokey, live-like, relaxed, full with emotion
* less precision, less detail in layering and imaging quality
* fuller at mid-bottom, full of energy 





This is a great resistor for tonality! It is comparable to the famous AB (Allen Bradley) resistors. It is great to be used as cathode bias resistor, grid resistors, or places where heat or power dissipation are lesser. You can still use that at hot places or as plate resistors, but you need to over-rate it substantially to reduce the temperature caused aging effects, or pre-age it by running it in first before matching. If all are considered, this is one helluva resistor for tube amp use!
