Measuring "across the filaments" means just that - measuring across the filaments. At the respective pins of the tubes.
For example, in the 41 tube, those are pins 1&6. Since all tubes are in parallel, measuring at any tube's filament will do.
This will ensure that the transformer in question powers the filaments to the expected voltage.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
