Re: Persistence seems lacking...

Graham, VE3GTC

making one own tubes is not easy but others have done so. A search of youtube will provides a few results - there was one French gentleman who had a farily long video describing his process and another that might have been multi part.

And transistors and IC's - that has been done too.

among a few (very few) others.  Indeed not so easy and perhaps not even very practical other than the "Look what I did" wow factor.

cheers, Graham ve3gtc
