[NJARC] Tubes for clinic

The discussion of impedance and reactance at have always been interesting to me and being a General Radio fan I found this graph helpful.   The graph is an analysis of a speaker, Reactance vs.  Resistance at audio frequency.  It might be of interest.
Below is a link to the General Radio 1603 XY Bridge manual.  The graph is on GR page 17 figure 5-4.  I've seen this graph reproduced in some other reference books but can't remember which.
