Members agedhorse Posted June 28, 2022 Members Share Posted June 28, 2022 I haven’t seen one of those amps in well over 20 years, don’t have any docs. Sorry. Quote Link to comment Share on other sites More sharing options...
Members Dookietwo Posted July 1, 2022 Members Share Posted July 1, 2022 If I remember right the crossover points were 800hz and 7000khz. I don't remember being able to defeat those either. Sort of a single use amp. I had an AB International President 900A and it was a great amp like most in the line. Let us know if your able to find a way to use it. I remember them as a very punchy, solid sounding amps. Quote Link to comment Share on other sites More sharing options...
