I don't know why I'm having so much trouble finding this. Could anyone direct me to any webpages/books on capacitor designs, their advantages, stuff like that?
I'm trying to build a homemade capacitor to replace the MMC in my DRSSTC because well, I'm cheap and I like to know about stuff. Currently, my DRSSTC is down, so I was testing my prototype in a small SGTC, it worked great but soon got hot. I was also wondering how to minimize ESL, ESR, etc.
Also, anything on homemade electrolytics? Yeah, probably not.

ISTR an "original" TC cap for the primary resonant circuit was made of a sandwich of stacked aluminum foil and plate glass. I recall seeing a TC with one of these 20 years ago.
I found a too-short mention of glass caps here: As always it's interesting reading, it explains the conical primary windings I see in "modern" TC designs.

Look on cap manufacturer's websites, through their app notes and stuff. They usually explain some of the manufacturing process, what substances are used (in addition to aluminum or tantalum) and such.

One can only burn up so many hand rolled capacitors before it becomes overwhelmingly frustrating. While I have had home rolled caps last a decent length of time the effort that went in to making them didn't seem to be worth their unstable nature. I too would suggest sticking with an MMC.
