Use the choke with the lowest DCR. I suspect the Ferranti is highest DCR.As for that rectifier tube, 5AR4 are rugged & my first choice or use GT Britain 6CA4.
Follow Ups:
urrr... not the one with highest inductance so as to block most ripples?aren't those with lower DCR (higher rated amperage) for power amplifier usage?
Both have high inductance. A low DRC is more important than a few Henry inductance at the two listed quite healthy values. To split hairs, if the larger one is within 10% percent higher DCR over the other, then use that one.
