Drawing tube symbols

Post by Robert »

Is there a correct way of drawing vacuum tube schematic symbols? I've noticed many style variations over the years and I am wondering if schematic drawing rules or standards were ever adopted by professional engineering associations e.g. the IEEE or ANSI.

I attempted to load (if that's the correct term) a tube preamp schematic into Kicad and while the provided tube symbols are nice looking, they're a little large and "European" looking. My attempts to edit the provided symbols were just plain awful.

Any advice would be greatly appreciated.

Many thanks,

Robert
