RE: Dowdy choke for an headphone/preamplifier.
Posted by mqracing on July 8, 2016 at 10:19:50:
The two inductors (plate choke & output trans) are in parallel.
What was the signal level and frequency that you used to measure the L? What test instrument did you use?
To get true inductance readings you really need to use a professional inductance bridge and drive the unit under test properly.
