“Martin, I agree but the diagram is still wrong as a single pin cannot have 1480 and .2 ohms. It would be 1480 and 740 ohms.”
When muted all pins are connected. That’s where the 0,2-0,3 Ohms come in.
When unmuted, the L- and R- are still connected (signal ground), so when measuring between L+ and R+ you are measuring the two coils in series.
Their common center connection to ground doesn’t matter, seeing as you are not measuring with respect to ground.
OP: Any access to another Beogram to test the suspect cartridge with?
Where are you based?
