RTA11TL Crossover

I'm thinking about replacing the capacitors in my RTA11TL crossovers.
Does anyone know the values?
I popped it open to check, but the yellow cap (in parallel with a 12mf electrolytic) is unmarked. I'm thinking of replacing this pair with a single metalized poly if possible.
I found a thread on RTA11T upgrade to "TL" which hinted that this may be 16mf (total) but I'm not sure.
Also- the resistor is unmarked.

Has anyone done a crossover update on this speaker?

    16mf mylar in the tweeter's signal path...

    Looks like mine have a 12mf electrolytic + 4 mf mylar (in parallel).

    I'm guessing that a single 16mf metalized poly would be an improvement.

    Thanks

    Yes a single 16uf is better than the 12 and 4 tied together.
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    I was referring to how Polk wired up my crossovers-
    they have a 12mf electro soldered in parallel with the 4mf mylar - the leads are soldered together. These are the two I'm thinking of replacing with a single 16mf.

    There is another 12mf in parallel with the resistor- for that one, I'm planning to use another 12mf poly.

    (also a 34mf poly for the woofer)

    Thanks.
