Does anyone have a link to this thread, it is time for the upgrade!

No link to the thread, but here is a parts list:

Solen PB series caps and Mills resistors (of course what brand to use is up to you):

(2) Polyswitches from Polk.
(2) 750pF - silver mica caps.
(2) 4.3uF - 400v caps.
(2) .1uF - 600v caps.
(2) 12uF - 400v caps.
(2) 20uF - 400v caps
(2) 39uF - 400v caps.
(2) 1uF - 400v caps.
(4) 7.5ohm 5 watt Mills resistor.
(2) 2.7ohm 5 watt Mills resistor.

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.

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.
