Description

The RCA datasheet attached to the first registration states +/- 90 V maximum peak insulation voltage between heater and catode. The same rating confirmed in a subsequent re-registration, 446C, in February 1950.

Superseded by 12AT6A for safe operation when heater is connected in series string to AC mains.
