Broskie "Unbalancer" - transformer specifications

I'm currently in the process of soldering Broskie's "Unbalancer" PCB:

http://www.tubecad.com/2011/11/25/Unbalancer 9-pin.pdf

On pages 13 and 18 he specifies what sort of secondaries are required for the transformers, however I am a little confused as to how I need to specify the windings to the transformer manufacturer (it is an r-core type).

The input tubes I am using are 5963 tubes, whilst the output tubes are 5965. Hence in both cases the closest recommendation as per the chart on page 13 of the manual is the 12AU7 - with a B+ of 240V. And an AC secondary of 330VAC. However on another page he specifies the following:

The power supplies require an external power transformer(s) with two secondary windings (120Vac to 260Vac and 6.3Vac to 12.6Vac).
Presumably he is assuming that the 330VAC is centre tapped?

The r-core manufacturer has asked for a specification in the following format:

Example

240VAC input

output
60 - 0 / 60 - 0 each 150ma = 300ma

6.3 - 0 / 6.3 - 0 each 1.5A = 3A


For the Unbalancer using 12.6v filament tubes - would this be the correct voltage specification?

240VAC input

outputs

330 - 0, 1 Amp (200mA for each tube)
12.6 - 0, 4 Amps (say, 1 amp per filament)
 
Anything between 200Vrms to 300Vrms, 50mA, is more than enough. Adjust R12 to suit.

(So you could use 200-0-200 up to 300-0-300, 50mA if you prefer centre-tapped transformers)

But i would need a high-V + low-V Glassware's PSU, isn't it? As newer Unbalancers no more include PSs...
Then transformer should have high-V + low-V secs. What voltages then, assuming i will use ECC802 input and 6CG7 output tubes?
If i choose a PS-15 PSU, that has 1x high-V and 2x low-V independent regulators, then i could use both low-V DC sources to power heaters at different voltages? Or i'll have to use just one anyway in 12.6V?
