Rerurn to Romy the Cat's Site

Who know how they die, at least I was not able to figure it out. The literature suggest that when gas regulator at the end of their life they stop regulate or maintain regulation but increase noise. I was not able to detect it.

I have many gas regulators and measured their mutual conductance. I take the measured 100% gas tubes and the very weak tubes (the same brand) and put them in Milq – they sound identical. I went further and was trying to intentionally kill one 0A2. I drove it for 3 hours with 150mA (instead of 35MA max). The tube went hot like hell but do you think it killed it? Very much not. It still regulated 150V and it after it cooled down it sounded perfectly fine.

Since I use gas regulation in my Melquiades to damp bias and bias compensator supplies I really would like to learn how the gas tubes die and what would be a signifying fact that a gas tune at the end or it life…
