Hello,
building a tube mic from scratch, I was looking for a way to firmly connect the very high impedance wires from the capsule to the rest of the circuit while maintaining the best possible insulation for them.
Here's what I just ended with :
From left to right:
- I took a good old vacuum tube from the EL500 family and exploded it with a hammer, cut to the desired length the wires connected to the pins.
- with the "diamond" cutting disk of my chinese Dremel copy, I started to cut and then file the glass around the kind of glass bubble/tube that encircle the pin.
- drilled the good diamater hole in the PCB so it just fit and stick inside ( I think I'll also add a drop of glue after).
One could say "don't waste your time, order a teflon one" . Right, but what can I say, that's what is DIY : it sometimes helps me feel my brain and my hands are... alive.
