Everything you wanted to know about .... / Re: The Tone Zone
« Last post by nienturi on October 16, 2026, 03:29:21 AM »So, the Tone Zone and the Air Zone have their coil specs reversed to each other. The screw coil of the TZ is like the slug coil on the AZ, and the slug coil on the TZ is like the screw coil on the AZ. Interesting. Also makes fine tuning the adjustable screws probably different between the two.
I think so. Because since than i have bought another TZ and here i write the measurements of it;
Measured DCR: 17,529 K Ohm (Series)
Measured DCR: 8,223 K Ohm (Slug Coil)
Measured DCR: 9,24 K Ohm (Screw Coil)
Inductance @100Hz: 8,79H (Series)
Inductance @100Hz: 3,8649H (Slug Coil)
Inductance @100Hz: 4,1907H (Screw Coil)
I still have that Air Zone in my inventory and this TZ, too. I can re-check.
