>>Sometimes the choke / cap is specifically tuned for line frequency and moving the first cap value can effect that. But it seems not critical in this instance.


Well. What I do not know (if you said that, I missed it) if your radio is "A" version (Canadian) or regular (US).

The canadian was for 25Hz, and so they used a much heavier iron core transformer, as well as larger 1st cap (10uF i/o 6 uF).
Whatever the case, your today's frequency is 60Hz (we won).

So if the radio is "A" and you use 10uF, you will unnecessarily raise the B+. The "6.8uF" seems to be the popular value that will do well.

Now as for the filter itself, it is not like it was tuned as one thing: the 1st cap is the filter's smoothing cap and then there is the addition LC filter which is the choke of the value on the order of tens of H, forgot , 25H or 40H and the cap that is, same as the 1st one, 6/10uF depending on the frequency.
As I said, I prefer larger one for the 2nd cap and an as close as possible to original's valuye for the 1st one (for 60Hz this time).

Another thing, in the 2x47uF pushpull version they used a 0.25uF cap across the choke. The thought, I think, is to compensate for the LC output ripple with the similar ripple 180 degrees apart.
Many of us are of the opinion it is not needed, so when the time comes to restuff cans, we do not necessarily use it, and larger 2nd cap valu will do just fine for it.

But yours is an SE version, and I do not see that cap in there.
