CJ Well-known member GDIY Supporter Joined Jun 3, 2004 Messages 15,737 Location California Dec 13, 2014 #2 here is inductance vs frequency at 1 V-rms, Henries will go up with level as this is a low input voltage, but we did not want to saturate at the 10 Hz frequency which would give a skewed graph, Attachments HS-56-Henries.jpg 59.8 KB · Views: 57

CJ Well-known member GDIY Supporter Joined Jun 3, 2004 Messages 15,737 Location California Dec 13, 2014 #3 what is the best level to run this guy at? we can graph inductance vs level at 20 Hz and find out, for a linear response we see that 4 V-ac looks about right, for a little mojo, (read distortion due to saturation) we may want to turn up the heat a bit and try 6 or 7 volts, Attachments HS-56-Henries vs Volts.jpg 71 KB · Views: 45
