Hi everyone, I have been given these caps by a friend who bought them off ebay for his amp, only they won't fit as they are LARGE.
I was wondering if anyone knows if they're any good.
They measure ~6.5 cm diameter x 10.5 cm high.
I can't figure out how to attach the image - help!!!! please!!!!

just it can be my foundings on actual bhc aerovox caps but it sounds pretty slow and very silky and even dull. .If you like sofdome tweeters sound it can be to yours taste. as for the best cap I would no rate it this high. I am ataching picture of caps that I have tested
seems it is are the same.
anyone who says that aerovox bhc is best cap should try siemens/epcos sikorel 105 or 125.
theese caps are the most dynamic cap I have ever try in high current class a power amp. i would put against any cap in this configuration. even black gate. and they slightly worst than bg in terms on transparency. I have lot of BG and in near future I will have arround 25- 30kg of black gate caps
so I can compare it in the same configuration BG vs sikorel in class a power amp. sadly theese prototypes will be dismountened because of cost(there is no logic or money to invest a 12 000eur in power suply capacitors)
I builded few amps with siemens epcos sikorel supply .it costed a lot of but it was worth.- frightening dynamic transients.
at the moment I am building new ultimate solid state class a amp with finest parts available . it will have 2x 28W/8ohm, there will be no parts paraleling and it will have external power suply box with 400x 1000uf 100V epcos sikorel . each 35x70mm the size of power suply is triple size the amp

I've tried a few caps in my UCD amp
Evox Rifa 200
BHC ALP20
BHC ALS20A
Siemans Sikoral
Philips Q types
Out of those I liked the Siemans Sikoral best but lately I tried the BHC/DNM 4-pole T-network caps and these are by far the best I've used
I agree the ALP20 and ALS20A had a smooth signature, not bad caps though.
The 4-pole T-nets are very dynamic when used properly

I think this is the same caps that my friend buy from schuro.de
I even did not test them because it said they are almost the same dull as standart bhc.
It very depends on aplication where you use cap. I use them in class a power amplifiers where real currents are 10-12A. there is no at close any cap I have tried. of course I try not every cap, at the moment only 20-25diferent kinds, I am still in searchnig better cap that sikorel. I hope I can find one day.

RS Online in Germany has a few Sikorels, including 10mF/63 V: http://www.rsonline.de/cgi-bin/bv/r...jleleimecefeceeldgkidhgg.0&cacheID=denetscape
This may indeed be one main factor. Looking at impedance curves for different diameters of the same cap brand I notice that the version with the smallest diameter (35,7mm) has a higher resonant frequency than the bigger caps. One possible option would be to parallel a bigger cap, e.g. a standard Epcos variant, with a smaller Sikorel cap:
