Default Bhc Aerovox - Any Good?

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!!!!

Hi

To my ears ALS20A are the best electrolytic capacitors available.

Great I'll give them a try.

Now to find something big enough to accomodate them

What have you used them in? Looks like I could only fit one in my Quad amp.

Thanks, Lee.

Hi

I have used them in a number of pre and power amps for the last twenty years. I bought a large quantity some years ago but do not seem to find them available now and have recently been using Kendeil.

I am sure you will enjoy building something with them.

Elviukai.

Why ?

Do you not agree?

I really could do with a few more opinions as I don't want to start drilling holes in my amp casing to fit these in if they can be bettered with more modern (smaller) components.

Thanks, Lee.

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

Yeah, I know what you mean. I have a sh*tload of caps from BHC (330uF and 470uF @ 385V) and there huge!
Although mine are not circular but octagonal or decagonal (8 or 10 sides)

Edit: not 8-10sides but the same as your attached picture but without the screw at the bottom.

Hi
In this case the caps are not just BHC aerovox; they are ALS20A which I think are the best caps Aerovox made. I find the ALS20A much better than other aerovox caps. The treble is silky and the base firm.
