I don't think that they did. Those would cost more than the usual AA5 miniature tubes.
The clock and AC-DC table radio used the regular miniture tube line up. The six tube sets, used a 35C5 and an additional 12BA6. The six tube sets were all hand wired, where some of the five tube sets were Pla-cir boards.
The portables, that had the oval speaker grill, used the sub-mini tubes for the osc-mixer, if amp and first audio-det functions. The output tube is a 3S4. It also used a Pla-cir board.
Some of the other portables were carry overs from earlier years.
