Sono tube source or paper tube source almost any size.

Hi all, I just finished my big DRSSTC and thought I would share this info with everyone. A company on the west side of Cleveland .....Acme Spirally Wound Paper Prods. ........is the source I used for my 12" tube. It is 1/4" thick and very ridged. Light enough so I can take the secondary off and on by myself including the toroid! I just ordered 6 pieces 12"dia X 72" long to fix my burned secondary on my spark gap TC.

The tubes are wound on a 12 foot long mandrel and then cut. You can get them 12' long if required! Very reasonable!
