FWIW I have found that best results are from dedicated transformers for each filiament. I would not even think of using a multiple secondary trans for DHT's.I use a split bobbin type only.The split bobbin gives very poof HF coupling in audio but is exactly what you want for isolation in filament supplies.I use a CCS for small signal tubes like a #26 and either AC as above or for the #10 a filament choke and DC.
