Description

A sturdy constructed tube designed to withstand shock We recommend this tube to manufacturers developing new sound heads as the preferred type for use in portable 16 MM sound-on-film The RS8 series is exceptionally dependable when used in in- dustrial electronic control equipment (such as counting, sorting, burglar alarms, This tube is supplied with a five prong octal type base and a TS bulb, dimen. This variant uses the S1 cathode surface described by the family datasheet. The V variant is the higher-voltage vacuum version listed in the maximum-ratings table.
