Original letter from Mr. SAM BENELBAZ

Dear iris,
i hope you are ok. 
I have installed the JFX capacitors last Sunday and i can now give you my impressions.

But first i have to tell you what speakers and amps i used for the test:

The speakers are YAMAHA NS1000M well known in the market and very revealing .
The amps are two american CARY tube amps model 40M using 6SL7 and EL34 tubes.
In this test the EL34 are NOS Philips EL34 of the XF2 series (the best).

The Yamaha crossover was using mainly NICHICON capacitors using metalised paper .
I did replace every capacitor with the ones you send me.
The CDs i use for the test are very good Cds , classic music and jazz mainly.
I know them very well and can hear the differences well. 

jb Capacitors Company is a leading ISO  9001:2008 manufacturer founded in Taiwan. produce top 
quality Film capacitors on market.

Film Capacitors

Film capacitors satisfy a large variety of electronic applications, data processing, because the dielectrics have excellent electrical characteristics, high stability and long life time. A film capacitor uses an 
insulating plastic film as the dielectric.Performance of the capacitors strongly depends on the dielectric material. The most common dielectrics are Polyester and Polypropylene. below are some our popular PET, PP series:

jb Capacitors is ISO 9001:2008 certificated professional manufacturer for full range of Film Capacitors and standard SMD electrolytic capacitors.

A dual run capacitor supports 2 electric motors, such as in large air conditioner or heat pump units, with both a fan motor and a compressor motor. The dual capacitor has 3 terminals labeled "C", "FAN", and "HERM" for the common, fan, and hermetic compressor connections.

Round dual run capacitors (shaped as round cylinders) are commonly used for air conditioning, to help in the starting of the compressor and the condenser fan motor. Dual capacitors come in a variety of sizes, depending on the capacitance (µF), such as 40 plus 5 µF, and also the voltage. A 440 volt capacitor can be used in place of a 370 volt, but not a 370 in place of a 440 volt. The capacitance must stay the same within 5% of its original value. An oval dual run capacitor could be used instead of a round capacitor, but the mounting strap should be changed to better fit the oval shape.

IEC/EN 60252-1 2001 specifies levels of protection for motor run capacitors
• P0 - no protection
• P1 - fail open circuit or short circuit
• P2 - fail open circuit only
