      there is a gigantic difference between voltage and current. the koss amp can deliver 2400vppss at 1khz into the koss headphones. it is...

      the maximum voltage for the headphones measured in vpss is 4 times the bias voltage of 580v before the diaphram goes negative. so 2320...

      kevin gilmore replied to the thread The Stax Thread III.
      the current source vs the resistors is in the 3rd stage (vas). the output stage on both the 717 and 727 are emitter followers with...
