Hi all,
Need a little help understanding a circuit connection. I am restoring a 39-116 console. The separate filament transformer 32-7993 physically has 2 primary leads and 2 secondary leads. The transformer is stamped as 32-7993 and is original. The problem is that the schematic has this transformer as 3 (three) leads for the secondary. The actual transformer has almost exactly 6 ohms between the two secondary leads that are there which is correct by the schematic but does not have the third lead as shown on the schematic, which is supposed to have less than 0.1 ohms and powers the 2A4 Filament. What the heck is going on with this transformer and this wacky schematic?. Examination of the leads inside the transformer's case shows no sign of there ever being a third lead in the secondary.
Thanks for any help
