Hi miguel, what do you mean with time delay? Surely not the heat up time of the tubes.
Othen than that I can't really see any delay option for the anode voltage.

By the way, the voltage rating of the smoothing caps is a 'bit tight'. I would use at least 600V dc.

Miguel, replace the rectifier tube with a silicone semiconductor, ad a timer relay to switch HT on only when the audio tubes have warmed up , approximately two minutes, then tou would have HT instantly.

Try an indirectly heated rectifier such as a 5V4 or 5AR4 to increase the warm up time of the rectifier.
