Measuring audio amp output power
Thank you, gentlemen.
So we're all agreed:
1. there's no problem using wire-wounds for a load provided the power
output measurement is carried out with sine waves from a suitable
external generator.
2. Even low rated power resistors can be used for the load provided their
case temperatures are kept low by some effective means of external
cooling (something more than mere heat sinks and fans, IOW).
Many thanks.
