The trannie's overall VA rating includes the HV and filament windings' combined maximum-loaded current ratings.
For tube rectified, 300VAC or 325VAC will work with the GSG design. For solid state, use 275 VAC secondaries.
If you want to make it as "stock" as possible, Triode Electronics may have some 240VAC primary "export" versions of teh PA774 power trannie.
I presume that India (as does most of Asia, Europe, Africa, Australia and perhaps some nations in South America), has 220 - 240VAC 50 Hz, so the 100VA rating is maximum, with the 60Hz power in the USA and Canada, and parts of Japan, one can get another 20% of out of them, according to AN-TEK's ratings..
Volt-Amps aren't necessarily the same thing as Watts, as some power factors may have to be figured in.
