Hi All,
In the mic preamp circuit, about halfway down this page: https://web.archive.org/web/20170831...-jfet-mic-pre/

...should the output transformer be left floating at one end as pictured?

No. It won't work like that. It's a error. The "floating" end of the
primary should be connected to ground.


Also, the output transformer I have has a center-tapped output, and the core is not broken out to a pin as pictured in the circuit diagram. Should I connect the center tap to pin 1 of the XLR socket instead?

No. Leave the center tap disconnected.
