Monitor 4 Cap Question

I recently upgraded the capacitors and resistors in my SDA2's and they sound amazing! I had so much fun, I decided to try it with my old Monitor 4's and also bought Monitor 7's for $95, but I need help identifying this capacitor from the M4. Does anyone know what it is? I tried looking at the schematics, but I didn't see the original M4. Thanks!

    It's an electrolytic cap..... :D
    You will need to look on the other side that is where the value will be.

    These are the original Monitor 4 that was manufactured from 1982 through 1984.
    The low pass filter for the MW6500 driver consists of a single 0.3 mH air core inductor.
    The high pass filer uses a 5.8 uF cap and a 0.4 mH inductor.
    The tweeter fuse is the standard 1 amp fast blow AGC style fuse.

    Hope this helps

    Yep. There it is. You'd think they could have put it the other way. :)
    Says 5.8MFD 50vNP. I'm assuming 5.8 microfarad 50 volt.

    Correct 5.8uf 50 volt non polar
    Sonicap has a 5.8uf that would work nicely. It will be higher voltage

    I finally got around to upgrading both the 7's and the 4's. There will be no pictures. I did a massive hack job on the wires and the soldering, and am embarrassed about how bad it looks. But as ugly as they are, they sound amazing! I had forgotten how great the peerless tweeters sound in the 4's. I promptly replaced my rear speakers with them. And I was thinking of flipping the 7's, but I might keep them. They sound too good and I don't want to show anyone the ugly crossovers. Thanks again for the help. I know I'll be needing more help in the future.
