It's used with a Philco 3 volt dry battery used with a model 37-33 battery operated farm radio. The number 41-8011 dry battery that Philco made for that set had a socket on the battery pack for that ballast tube. The set was originally intended to use a 2 volt wet cell.
Philco did all kinds of strange things, like incorporating the B and C batteries in one pack, instead of individual batteries.
