I just realized that you talked about Mullard 5-20 POWER transformer, and not about "Merlin" OPT...
Well, nothing complicated with PT - usual 5V rectifier winding, two 6,3Vct heater windings and 410-0-410V HV secondary, GZ34 rectifier, CLC "smoothing". OPT is UL, 2xEL34 cathode biased, input/driver EF86 to ECC83, high neg. feedback.
There`re a few pages of descriptions/comments in M. Jones book(s). Of course, the full schematic/descriptions/construction, measured performances...etc - in "Mullard Tube circuits for audio amplifiers" book.
IMO - go for "Merlin V2" :-).
