Matter of fact, the windings of the two tubes to be tested can be cross-connected as one circuit so that induced power is identical
* Start with an 1800 watt induction “hob” or hot plate - $70 from Amazon. http://www.amazon.com/Rosewill-1800-Watt-Induction-Stainless-RHAI-13001/dp/B 00GTZMHOW/ref=sr_1_2?ie=UTF8&qid=1426860024&sr=8-2&keywords=induction+cooker * Use Kanthal windings on both tubes - of identical length and turns. Current is induced into the Kanthal wire by the hob. Then test the two samples in different orientations, but always side by side on the hob so as to eliminate the complaint that induction coupling is not the same for both.
