Could you tell a bit about how does this: "I end up with 360V on B+, 15K plate load, grounded cathode, 160V on plate and -3.5V on grid via a series battery." sound as compared to the normal Milq bias?

I did the following.

As a battery I use 3.5V Lithium single cell from computer supply. I did not build the Milq-type bias on the 2A3 amp and I can’t compare Milq vs. Battery bias on this amp. In a past, when I made the first Milq I did experiments with Milq vs. Battery. I do not remember the details already but obviously the Milq bias won. With this 6E5P-2A3 amp it looks like the Battery bias is more interesting then cathode bias. However what made me pissed is that the magnitude of details behind that “more interesting” has completely escaped me as my speakers do not handle any “fine moments”. The batteries are a tricky thing. Theoretically battery is an always charged capacitor, so in my case the signal flows via this capacitor. It would makes to compare the battery with fixed bias of non-Milq style, and perhaps a different type of batteries but I really can’t do it with my current full-range speakers.
