Smoke it and see.
Try a bridge/big cap feeding a 300B, then hook it up to a scope or annoyingly efficient speakers.
On the last Wavac 300B amp that I serviced, trimming the hum pots was essential to obtain the lowest noise level, and this had a set of filament supplies consisting of a chassis mount bridge and large cap soldered to it, much like the OP's link.
I did also check to see if the pots were perfectly centered, and they were not.
