I readily know that all 3 amps are based on the same design.And that the power supply issues exist trying to go from a high current power supply design to a high voltage design.I am trying to modd a 2250sx to a high current design (2100HCCA or Concept 97). Any info would be helpfull.
Transformer ratio
Zener diodes for power supply regulation
Resistors near center of audio section 220 ohms >> 150 ohms
The 97.3 is rated to go down to low impedances but the one I worked on had rail voltage similar to that of a 2250. At low impedances, it would have failed very quickly.
