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….
