Capacitor p0rn

[adamct]

Here they are, boys..... 

Below is a 200uf metalized polypropylene motor START cap that I bought by accident. These are NOT suitable for use in the Crack. They will explode if you try to install them. This one is shown here just for fun.

Below is a TEMCo 100uf oil-filled motor RUN capacitor. I plan on using two of these to replace the last 220uf electrolytic in the Crack power supply (i.e., the cap on the far left when looking at the underside of the Crack with the power supply on the far end of the chassis - the same view as in the manual).

Below is an Icar 200uf metalized polypropylene capacitor rated for AC and DC. I plan on using two of these, one to replace each of the other two 220uf electrolytic caps in the Crack power supply.

Left to right: Icar 200uf metalized polypropylene; Temco 100uf oil-filled motor RUN cap; soda can (sorry, all I had handy); Chinese motor START capacitor (Note that the small blue cap with Chinese characters is a motor START cap and therefore NOT suitable for use in the Crack).

ClarityCap 100uf 630V metalized polypropylene caps (Used in my Quickie)

The ClarityCaps are much bigger than they appear in these pictures. In particular, they are extremely wide/fat.

In case you're wondering, I have 100uf Clarity Cap ESA 250V caps as coupling caps in my Crack, and 2.2uf Clarity Cap ESA 630V caps as coupling caps in my Quickie.

Enjoy!

FYI, other than the ClarityCaps, all of the caps pictured above were $10-15 each on eBay.

The large size of the studly caps,  bodes well for your intended use...John

Clarity caps are Manly caps!

I forgot I had these.  Tried them in a speaker but they weren't a good match with the tweeter.  If anyone wants them let me know.  It's a pair of 12uF and 15uF Clarity ESA caps in case you have trouble reading the labels.

I have some clarity ESA's in the foreplay III...  They were obnoxiously bright in that application as well for the first 150 hours.

I 'mona have to post in this thread.  I'll take pictures tomorrow.

Here's mine.

Just changing the coupling caps.  I have no problem with electrolytics in the power supply.

Can't wait! I look forward to it...

  Now boyzzz,  is bigger better? Don't you it's how you use it that counts?

 

[earwaxxer]

I still like the Duelund - not to give you guys a complex or anything!

 

[Grainger49]

Ok, maybe mine's not bigger.  They have a lot of capacitance.

The Dueland are just obscene! 

Left to right: ?uF @900V DC, 1000uF @400V DC, 1400uF @450V DC 2200uF @400V DC and Diet Coke, decaffeinated.  Who knows how many V DC it is rated at?

Ummmm....yeah. Sure, Greg. Keep telling yourself that. Whatever helps you get through the day....

;D

 

[adamct]

Those Duelunds are crazy. What capacitance are the ones pictured? They don't even make them in high values, do they? So those gigantic things are...what, like 10uf?

Grainger, are those electrolytic caps? I like the looks of that one next to the Coke can...what can I say, I like shiny things!

 

[matthewmckay]

I have a thing for the russians..

Those aren't caps.  They're coffee cans in disguise.

I have some clarity ESA's in the foreplay III...  They were obnoxiously bright in that application as well for the first 150 hours.

That's surprizing.  I've never found the ESA caps to be bright.  I found them to be a bit dark in the upper treble. 

 

[earwaxxer]

The duelunds are 300uf - probably the biggest they make. Custom order I'm sure!

 

[matthewmckay]

The ESAs have mellowed out nicely.. perhaps something else in the chain was exacerbating the problem.  I have been tempted to grab some mundorf SIOs for it but havent managed to pull the trigger.

I am also interested in trying these.

I have not heard of those... Kind of pricey for a no name! I would steer clear....

I need to hang a pair of those under my truck's back bumper. Don't MESS with me!
