Resistive measurements were made on A15 high temperature superconductors. Anomalies indicative of a phase transition were observed at 433/sup 0/K in a single crystal Nb/sub 3/Sn and at 485/sup 0/K in an unbacked Nb/sub 3/Ge sputtered thin film. Results are compared with the high temperature transmission electron diffraction studies of Nb/sub 3/Ge films by Schmidt et al. A possible instability in the electron energy spectrum is discussed.
