| Descripción |
The advertisement in "Radio" Nov. 1929, page 61 shows that this tube was fitted with the patented ceramic Perryman Bridge. This was two special spacers, one placed between the press and element base. This had the necessary wires passing trough it for sturdiness, insulation and parallel alignment. The second bridge was placed on top of the element structure. This element structure would have been expensive to make and it is not known how long this tube variation was commercially available.
