Hello,
What are the best ways to non-destructively get information on audio transformers? I've fished a 10 turn winding around the core, as RG Keen recommends to find the turn counts. Promising results there.
The biggest problem I'm having is getting a consistent measurement of inductance. Just touching a coil for several seconds sways the measurement a large amount. Is there a formula to measure the core temp and standardize inductance measurements made at various temps? Resistance varies too, but not as much.
