How to Make a Triode Valve at Home

Complete video of making a Triode with primitive materials in the home shop. Please skip around the boring parts because I wanted to include everything involved. I made a mistake in the glasswork which resulted in the envelope being very thin, the next day when testing the envelope imploded. I have since figured out a way of expanding which does not result in a thin envelope. Another Triode that I have made since works identical to the one in the video but has much thicker glass to make a more resilient tube.
