Where to get audio caps in correct farads
I've done so many searches, I gave up. I always find 47 MFD or 33 MFD, or 4.7 MFD but never what I need for my Infinity RS1 bookshelf speakers.
I need 45 MFD (uf) 50 V 10% radial, 30 MFD (uf) 50V 10% radial and 4 MFD (uf) 50V 10% radial bipolar electrolytic caps or better. Of course reasonable prices as these speakers cost me only $100/pair on clearance back in the late 90s. If I could recap them for $10 to $15 per speaker, I'd consider. These Infinity RS1 speakers are by no means as good as my Current Polk TSI100 speakers but did sound good when new and was thinking of recapping them for the fun of it.
Thanks.

2 x 22uf in parallel 44. Close enough for the 45
2 x 15uf in parallel 30. Done- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -
He wants radial caps.Political Correctness'.........defined

Yes, caps need to be radial as there's no room to add additional components. So where can these caps be bought??On to new and better adventures

Not to be rude, but makes no sense to me. Are you trying to stick them on the old circuit board? Slightly nicer axial lead parts with a lead ext will do the job.
3.9uf will work for a 4uf.
Spending 15 dollars on junk parts is just throwing away money. You can spend 50 and actually net some positive results- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

These are small bookshelf speakers, not much room to add parts that stick to far off of board. Plus I haven't found any in radial or axial that meet or exceed the specs.
Makes no sense to spend more on parts than what the speakers are worth. I'll probably just throw them away. If I'm going to spend $50 on parts, I'll spend $100 on new speakers and get better speakers all the way around. Then again, I don't need speakers. This was going to just be something fun to do, but not if it's not worth it.On to new and better adventures -
Yet still no one can point to a place to buy decent audio caps in the ratings needed.

Actually, it does. Speaking from experience. -
You can most times get better sound with $50 worth of parts and a little time than you can spending more money on another pair of speakers.

Dayton metallized polypropylene axial leads, 4.0uF +/- 5%, 250V. $2.09 ea. Leads are long enough to bend one back to simulate a radial cap.

30uF $10.59 ea.

47uF +/- 5% . Ask them for ones that are on the minus side. $14.29 ea.

If these are too big to fit I'd get a piece of 1/4" Birch Ply and do point to point wiring.
Total cost $27 per speaker. You said you're original owner and you like the sound. It's a hobby.George / NJ

So this is what you have to work with? Yeah you need to do point to point with a new board.

Poly caps are going to be much larger than the electrolytic caps used from factory. So if space is a large consideration then stick with the electrolytic caps. IF this is just a cheap fix with no intention for better sound along the way then by all means visit the Erse website.
As for "worth" I took 800.00 speakers and put 1000.00 worth of new poly caps, non-inductive resistors and new better closer matched inductors plus new wire and couldn't be happier.
please do not sell the speakers short they may just surprise the heck out of you with much better caps. -
A 3" x 3-1/4" capacitor extension 1/8" birch plywood or blank perf board mounted on standoffs to the original can house the two large Dayton's and the small 4.0uf can probably fit onto the board in vertical mode. You can replace those two ceramic resistors with non inductive wirewound ones without spending too much more.George / NJ
