Philco 40-120C Restoration
#9

With these values I think you are OK; the Cmax for this tube is 40uF.
Your Vbb could rise a bit, but probably not too much.
I would use 33uF as the 1st cap and 47uF as the second. Provided the voltages of both are adequate.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
