I use 100Hz for bass and 400 Hz for guitar amps and 1 hour duration but I'm concerned about what sine to in-use equivalent percentage I'm using a/ to accurately represent periodic in-use signal rather than the more stressing continuous signal . b/ under or overstretching the amp -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |
