80uF - cheaply. Possible?

[Psychobiker]

Alrighty,

So my trip to Addison in Montréal today yielded a slew of things, but I didn't manage to luck out on the 83uF caps I bought being non-electrolytic types...sometimes the motor-run type are foil/polyprop etc, but unfortunately these were motor-start electrolytics and must be returned.

Now, during my rummages tomorrow, I may well find something, but I don't reckon so, and 8x20uF Paper-in-oil at CA$10/ea aren't going to cut the (financial) mustard for this poverty-stricken project. There's no saving those horrid electrolytics by bypassing them with a .1uF poly-type, bypassing is irrelevant at AF largely. Oh woe.

These are in the bandpass (mid) section of a 3-way 1st-order system, and hence any 'iffiness' is going to be seriously noticed between 200Hz and 5kHz.

That said, beggars (someone here in Montréal please aid a starving graduate EE!) can't be choosers.

Here is 82uF poly cap

And if you don't mind non RoHS, a couple of these are about half the price

You could do a lot worse than the axon caps at parts connexion AXON True Cap Metallized Polypropylene Capacitors 82uF $13.82 each Its funny as I have been trying to find a way of smoothing out the lump in the freq response of my MTM's between 900 and 1600 hz and with the sims I've done so far an 80uF cap seems to be in order, so I'd been checking recently

How I missed that, I have no idea. Solen are just down the road from me!
Now, if those so-and-sos at Addison won't refund me, then those electrolytics will just wind up in a PSU or something...

Thanks again!!
