Introduction of Mr. SAM BENELBAZ

French, retired, have the hobby of TUBE do it yourself; used to work in IBM as a professional 
of electronics; after that for LASER a company involved in point of sales solutions and hardware maintenance, in that position, he bought a French company sic-safco. 

Mr. SAM BENELBAZ is member of some forums in US and France, some are AUDIOASYLUM.com and DIYAUDIO.com fun withtubes. com and some others.

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. 

Now lets come to the findings:
The JFX have good audio imaging and you can hear obviously more details than with the nichicon .
I think this is because they are wounded very tight.
Congratulations to the worker who did the job.

At this very moment i think that JFX are very good capacitors for cross overs and with their price-sound ratio you can go to the market without any shame.

My best regards

jb Capacitors Company Most Popular PET, PP Film Capacitors

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:

PET (Polyester) 
JFA - Mylar Polyester Film Capacitor: Cross to CH11, widely used in lighting and lamps.
JFB - Metallized Polyester Film Capacitor: Cross to CL21, K73-17, Vishay MKT368, MKT 467, MKT 468, Epcos B81130, B32921~B32924, Vishay MKP3362, Panasonic ECQU
JFD - Box Type Metallized Polyester Film Capacitor: Cross to Arcotronics MKT R60, R66, Wima MKS3, MKS4, MKS10, Epcos B32520, Pilkor PCMT 468, Iskra KEU 1930, KEU 1910
JFE - Mini Metallized Polyester Film Capacitor: Miniature size, non-inductive, epoxy dip coated

PP (Polypropylene)
JFL - Metallized Polypropylene Film Capacitor: Cross to Wima FKP3, Epcos B32612, Pilkor PCMP 489, PCMP483, Pnasonic ECWF
JFP - High Voltage Metallized Polypropylene Film Capacitor: high voltage, good option for high AC current applications
JFQ - Box Type Double Sided Metallized Polypropylene Film Capacitor: Cross to Arcotronics R76, Wima MKP10, FKP1 , Vishay MKP1840, Epcos B32651-B32656, Pilkor PCMP 384
JFV - X2 Metallized Polypropylene Film Capacitor, ENEC, VDE, UL: Cross to Arcotronics R46; WIMA: MKPX2,MP3X2; Epcos B81130, B32921~B32924, Vishay MKP3362, MKP3382, Panasonic ECQU
