Hi all, I've finally removed the audio transformer from the Taz for some measurements (shout out to our kind lab technician) but I'm bad with the math, so I'll need the collective brainpower from the thread...
Here are the conditions that I measured the transformers with:
Open (no) load
1khz
Megger B131
Here are the measurements:
185~186mH across the full primary/secondary under no load at 1khz with a Q-factor of approx 1.18
47.8mzh across primary/secondary to center tap under no load at 1khz with a Q-factor of approx 0.96
If I use 2πFI to calculate the Inductive reactance, I get an impedance of approx 1k, which means the transformer is a 1:1, 1k:1k transformer, can anyone from the thread proof the math cause it does sound very off to me
p.s. I forgot to measure the DC resistance of the coils
Many thanks!
