AUDIO NOTE™ TANTALUM RESISTORS

These exotic resistors from Japan, sound less dry than the metal films and they do not emphasize any particular frequency range. They sound more natural, more musical. They work equally well in semiconductor and tube amplifiers.

1/2 WATT TANTALUM RESISTORS
The 1/2 watt Audio Note tantalum resistors cost £2.80 each.

They work equally well in semiconductor and tube amplifiers. Most customers, who have tried the tantalums, say that they would never go back to the common metalfilm type resistors.

AUDIO NOTE™ 1 WATT TANTALUM RESISTORS

The AUDIO NOTE™ 1 watt, 1% tolerance, tantalum resistor values are £5.50 each.

AUDIO NOTE™ 2 WATT TANTALUM RESISTORS

In many applications a 2 watt resistor sounds much better that it is 1/2 or 1 watt equivalent, we use 2 watt resistors consistently in many places in our higher Level finished products, rather than the smaller wattage for reasons of sound quality only. These have a 1% tolerance. The AUDIO NOTE™ 2 watt tantalum resistors cost £8.00 each.

HOLCO RESISTORS


Holco metal film precision resistors have been used in hundreds of classic High End audio components over the past twenty years. They give a crisp, full sound; about as good as it gets in a metal film type. They are used heavily for military use hence the exceptionally close tolerance at 0.5% - 1%. They have low reactance, long term stability and can withstand high voltage pulses.
These resistors have a superb sonic performance. With outstanding musical qualities. Holco resistors are made with no ferrous material. Utilizing the closely controlled production process, the metal film is vacuum deposited on a ceramic substrate whose ends are gold plated. This is then joined to the copper end caps and leads. Hence they are non-magnetic. They are very popular with stepped attenuator a great endorsement to their quality as steps really do test resistors. We recommend that you do not bend the leads close to the body of the resistor, allow 5mm of lead before bending.

Allen Bradley RESISTORS
Quantities of these "New Old Stock" carbon composition resistors are limited, production has now ceased in the USA. Allen Bradley resistors have a huge following of D.I.Y valve hi-fi builders and guitar amp enthusiasts. A huge amount of old manufactured hi-fi were built using these resistors, hence these antique carbon resistors are close to the hearts of many. They were used heavily in vintage Fenders, Marantz, etc. Allen-Bradley is considered by some to be the best example of this type of resistor with Stackpole and IRC close behind, these carbon composites are equal in quality to those found in most classic valve equipment.
Carbon Composition Resistors particularly those manufactured by Allen Bradley are becoming more scarce and are in high demand due to their unique characteristics. They are known for their very clean and natural sound.

As stated Allen Bradley resistors are carbon composite, being made of an organic material they do have the tendency to absorb water from the atmosphere. This absorption can increase the actual resistance of the component, hence the slightly higher than normal tolerance published on this page. To fix this simply remove the water from the component and seal it. The best method is to place the resistor/s on a baking tray set, your oven to 80 degrees centigrade and leave in the oven for 8 hours. The secret is to remove the mositure slowly if you rush it it will become noisy in circuit.

KIWAME RESISTORS
These are an excellent match for Hi-End Audio. Kiwame resistors are from Japan and characterized by lower noise than metal film resistors and a more natural sound. There is a growing enthusiasm for these carbon film resistors because they recapture the vintage tube sound without the drift of carbon comps. They are also very compact given their wattage rating. The resistance material is carbon film with coated silicon and finished in green.

Mundorf M-Resist™ SUPREME Resistors

The MResist™ SUPREME series is specifically designed for high-end loudspeaker and amplifier applications. With their superior audio quality – as described by some of the most discerning designers and fine-tuners. This amazing range of resistors align with the same high standards as Mundorf`s capacitors and inductors.

Rated at 20 watts, these wire-wound resistors are non-inductive achieved by bi-filar winding technology.

METAL OXIDE LAYER RESISTORS
Unlike ordinary wire resistors, metal oxide layer resistors have no residual inductance. This means that they should always be used for all applications calling for high transient rise times, such as mid-range speakers and tweeters. Our metal oxide resistors have continuous power ratings of 4 and 10 watts, but their peak capacities are much higher.
