I have used power transformers when I have needed large transformers for 70V PA systems. Because we know the LF response will be OK. But do not expect mush past 7KHz.
Also because the power transformer people do not care about hysteresis at lower levels, there may be quite a bit more distortion at lower signal levels. They are OK for an emergency but not for long term use.
