Now over 22ma nice glow, to bright maybe. voltage drift gone.

I think you might have closer to 5mA before. I did see that with low load I had voltage
drift. Interesting is that this effect only for 150V gas tube, the 105V gas
tube are most stable at low currents for some reasons. As I said above at
15-25mA they do just fine. Feel free to play with tube rolling, particularly
the negative supply tube – it will affect sound to a degree. BTW, I hate to say
it but the best sounding tubes I found have the sexiest glow….Rerurn to Romy the Cat's Site
