Hello,

I'm about to wire up a pair of LL2765 and am wondering what the stars in the schematic mean, as I've never encountered that symbol in a transformer diagram before. Is it a phase dot indicator or something?

https://www.lundahltransformers.com/wp-content/uploads/datasheets/2765.pdf

There's one on the anode pin in the primary section and pin 2 in the secondary section. I'm wondering which pin in the secondary goes to the L or R tab on the headphone socket and which goes to the common ground tab.

Thanks,

Jeff

Thanks Bas, Per Lundahl uses this in several connection diagrams to make the phase easier to follow.
