SCR Company (Societe de Composants Record) has a past that goes back to 1936 ! Their know-how stems from the merge of three companies:

SETA, 'Societe Electro Technique de l'Anjou', specialised (since 1936) in resistors for use in electricity and electronic industries as well as in high quality hi-fi.

LCSM, supplier (since 1955) of special-use capacitors for various applications such as lasers, cardiac defibrillator and railway signalling.

RECORD, created in 1949, famous for manufacturing of capacitors dedicated to several applications like high quality hi-fi (tube amplifiers, passive filters for loudspeakers), ventilation (VMC with capacitors of two or three capacitance values), electronic variators and non inductive filters.

In the years that followed SCR gained the commitment of several audio industries.

At present SCR is the only manufacturer when it comes to high capacitance values at voltages such as 630 V ! These capacitors have become the sole choice for high voltage audio power supplies.

Depending on the dielectric and conducting material SCR capacitors are offered in various series :

PPE Series, distributed around the globe under several brand names and the label 'FAST CAPS'. This series provides a very low tolerance value of 5%.

TIN FOIL Series. Best known products of SCR, this series incorporates a pure metal foil as the conducting material instead of the usual metallized plastic film. Tolerance values as low as 1% and 3% ! What is really interesting about them is that they offer very low distortion artifacts, series resistance and high burst currents. Due to their construction they are relatively large-sized and quite heavy. Many designers employ these capacitors in coupling applications and as the main series capacitance of high pass filters driving tweeter drivers.

TEFLON Series. A rather new and quite promising series with TEFLON dielectric material. SCR research addresses the technical issues related to the operation of capacitor dielectric materials.

TEFLON + TΙN FOIL Series. With this entirely new product series, SCR attempts to combine the two 'worlds' with excellent results

 

However, we at MTZ Audio kindly warn you : if you are looking for   cheap capacitors from Eastern Asia with or without a famous brand label, this is definitely NOT your choice !

A new series of 2-Watts and 5-Watts resistors manufactured under very strict quality control in Japan only.

MTZ Audio is the exclusive distributor of Kiwame products in Greece and Cyprus.

Kiwame resistors are made of carbon film and their case is actually the first one for use is audio applications with superior specifications!

  Considerably low thermal noise levels, lower than metal film resistors!

  Lower distortion artifacts

On the other hand they offer true 0.5% tolerance despite their nominal E24-series 5% label ! If you don't believe it a multimeter will certainly convince you.

Their sonic character can be briefly described  as follows :

Effortless reproduction ('non fatique') subjectively perceived as an increase of headroom.

Extensive neutrality

 

Other interesting features of Kiwame resistors are the following :

The outer layer that surrounds the conducting carbon film is a silicon compound.

The maximum operating voltage is very high; some 500Volts for the 2W package and 600 Volts for the 5W package ! In addition they can withstand voltage surges up to 1000V (2W) or 1200V (5W).

Since their first introduction in the audio industry they have managed to gain reputation and the respect of both manufacturers and worldwide diy-ers.

In fact several manufacturers openly suggest Kiwame resistors along with the 'usual suspects' (quality capacitors etc.) for the upgrade of their products.

  Lately Kiwame resistors found another audio application, that of the step ladder attenuators used as volume potentiometers.

Browsing internet audio fora and DIY discussion groups proves that Kiwame resistors really make a difference!
