multi mini capacitor array

[deriver23]

Is it possible to build a "stiffening" capacitor from many smaller capacitors? if so where could i get capacitors cheap enough to use but not small enough that i would need an unmanegable amount?

It's not only possible, it's prefereable. You'll almost always get lower ESR for the same capacitance. The only downsides are the size and complexity. For cheap capacitors, try surplus places. I've used all of the people below with good results.

If you don't find what you need on the websites, write or call. They all have lots of additional items.

I used the large can 89000uF 30V each and paralleled six. a little over half farad in all. works fine.

Let all your friends/neighbours/co-workers/church family/family etc. know that you will take old electronics off their hands. Time with a soldering iron yields all manner of useful passive components, capacitors included.

what kinds of things should i be looking for i have a few old vcrs but they didnt have anything that large in them. Also a desoldering iron works nicely

[Stocker]

preferably, for large capacitors, high power audio amplifiers. alternatively, older test or medical equipment or computer stuff.

I've got (3x) 35,000uf and (2x) 86,000uf caps on my sub amp..
You can find them cheap at the surplus places.
