Hi,

The DRD circuit is not especially harder than others, the voltage across the 300B is cold is more, but for 300B I would suggest a slow warm-up rectifier (GZ34 etc.) or a delayed start for the HT no matter what, as full HT on the cold 300B is likely not the best thing, no matter what.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
