The All American Five I first saw used a 12SA7 converter, 12SK7 I.F., 12SQ7 detector/first audio, 50L6 audio output and 35Z5 rectifier. The lineup was changed - I suspect circa 1950 or so - to 12BE6, 12BA6, 12AT6(?), 50C5 and 35W4(?). Not challenging the loctal comments but I never saw one myself. - JimT
