How's that C-56U going to fit into an already crowded Dyna MK3 chassis? Never mind the ongoing controversy about non critical choke I/P filtration.
I suggested the 5R4 because it, like the 5AR4, draws 2 A. of 5 VAC filament current. A 5U4 draws 3 A. and I was uncertain about the power trafo's ability to provide 3 A. It seems the trafo can provide the requisite 3 A. and, specifically, the 5U4GB is a reasonable option. Of all 5U4 variants, only the 'GB is rated for 250 mA. of B+ current, like the 5AR4 and 5R4 are.
If the OP sets up the 1st position capacitance with 5R4 limits in mind, he can try both the 5R4 and the 5U4GB to see which of the 2 yields the best result.
