Questions

How big is the Centretappedtrafo PCB?

It measures 54 × 39 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Centretappedtrafo use?

13 parts, built around the 1N914WT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Centretappedtrafo KiCad files?

From the Preimtime/Project_CRT repository on GitHub, at the commit this page was made from: the board is Chapters/Deflection/PCBs/Centretappedtrafo2x/Centretappedtrafo.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Centretappedtrafo design in my own project?

Its repository states no licence, so its author keeps all rights: ask Preimtime before reusing the design.
