The red wire is too complicated. Copper wire plus some other ingredient (like the Tin and solder) is ok, but the vacuum tube is too much. Especially as red/green wire is free if you blueprint/copy

i was planning on them being an intermediate later down the line, which is why they are complicated

i dont mind if you make them an intermediate or more complicated, but the cost is too high, especially early on. I could make a few, made some errors connecting inserters and belts, and they get destroyed, you dont get them back. Later on you automate them, and all is fine.

i increased the amount you get to 15/craft in 0.1.06 or 0.1.07

thnx, thats a good compromise
