Jim,
I mostly listen to DHTs and headphones (Beyer 600ohms) and Magnequest TL-404, a 2W rated autoformer, so you have to run a DC blocking cap. The TL-404 has taps at both speaker level (4,8,16,32) and also at line level (125,250,500) and presents a 5,000 ohm load end to end, so it's ideal for a 45. I use various plate chokes, usually a Magnequest EXO-010.
I'm a pathological tube roller so I rotate through 4P1L, 1LE3, 1N3S, 1J6G, 6P21S, 01A, 12A, 26, 30, 31 and subminis like 5676, 1P24B, etc. I use batteries and DC wall warts for filament duties.
Sowther has variety of multi-tap series and parallel feed transformers. On the cheaper end of the spectrum I've had good luck with Edcor GXSE5-600-15K, GXSE5-600-5K and Carnhill VTB2291.
