Actually the Loctal tube series, with number beginning with "14" are 12.6 volt tubes, at 150 ma, I'm not sure why Sylvania did this anymore then why the ones beginning with a "7" are actually 6.3 volt tubes. To make matters more confusing Sylvania made some 6.3 volt loctals in their "7" series with 150 ma heaters, like in the PT6, but there were others that had 300 ma heaters as well.
