Update on Psvane Replica WE101D/101D-L filament voltage/current:
Just had discussion with Psvane tube factory - they will produce the new commercial batch in Feb 2014 all to filament 4.5V/1A spec then there won't be compatibility issue with all 101D amps.
Please note that the batch sold at Guangzhou audio show is of Filament voltage 4.15V/0.5A - this may not work for some amps at least not with Supratek as I got email confirmation from Mick - Supratek Cabernet has spec 4.5V/1A for 101D tubes.
