    I would use sonicaps over the solens for the smaller values, or Dayton's. Also use ther 12 watt mills. Ditch the Poly switches, and 750pF mica caps.
    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
    Ben

    I concur. Some feel you shouldn't mix caps after hearing my 1C's I don't agree in this case. My 1C's have Sonicaps on the high end (delete the (2) 750pF - silver mica caps, not needed anymore) and Solens for the bass circuit. Delete the polyswitch if you have high current amplification and won't get too crazy with the volume.

    They sound absolutely amazing and I wouldn't hesitate to do it.

    I also agree, avoid Solen for the highs. If you're on a budget, Dayton is ok.
