Recapping my old Videotone Minimax

I'm restoring my ancient Videotone Minimax speakers. Crossover has two 10uf caps in series: may I replace them with a 4,7uf (+0.33uf) capacitor?

An externally hosted image should be here but it was not working when we last tested it.

Also, how about these: they are Telecon and I don't know them.

If you use a single 4.7 uF you will need a non polarised type ( a capacitor that can work alternating current ) and if you do so you will not need the 0.33 uF

Tolerance on this kind of part is so big it will not make any kind of difference.

Yes, the math works. You could get a 250V film cap ($4-7) or a good bi-polar like an Elna 100V would be even less expensive ($1) .

Either way it would be an uncommonly good upgrade. Even cheaper are these from Parts Express.

Make sure to keep the voltage rating on all the caps in parallel reasonably high, 63V or higher would be more than enough.

Best,

Erik
