Anyone have a suggestion for a meter that won't break the bank.
I have a pile of caps that I need to identify.
Thanks

when i go home, ill see mine, its a sick one with everything under the sun. it cost like 40 and for 45 theres an autoranging one. (get that one) it even does capacitance up to like 220mf

I use an old Eico 950b Comparator. Got it cheap on ebay with manual. Don't remeber maybe $15 - $55??? Pretty cool if you're into vintage equipment.
New digital stuff is quicker and easier to use. The old stuff makes you slow down, pay attention, set the right range, and read the corect scale on the dial. Makes you pay attention. Maybe that's a good thing.
It also tests the cap @ full voltage, up to 500 volts.

I use a sound level meter. Charge up the cap, stick it on my tongue see how loud I scream. There is a point (with the really big caps) where all the muscles just tighten up and I can't say a word. So my meter is useful only up to a certain point. Trick I learned in the army, mind you, we used to use it on different set of body parts.
That AES meter looks pretty interesting. Measuring down to 0.1pF at 5% tolerance - thats pretty cool. For $40 I am in. Doesn't look as much fun though.

I like this one from tubes and more.
I've been looking at that one for about a week.
That seems like a better option than hooking up a charged cap
to my BIG H^IRY B^LLS and reading a DB meter

AHH!!! he said it out loud!!!

Hey Tuber...How many DB's are you worth with a 50uf 500v E-cap?
Since you are the glow in the dark Mountain Oyster Man.

For What It's Worth Department
I received my YFE Capacitance Meter from www.tubesandmore.com
It is a solid built and completely accurate peice of equipment.

Awesome, I just ordered mine. I am a real sucker for test gear. Actually that is the sole reason I build sloppy guitar amps, so I can buy more gear to test them with.
