Hi,
how does sap15 vary from sap16? I have 16 data.
Give me some data to work with and I'll do some numbers.
Vdc @ quiescent,
smoothing caps,
regulation,
maximum heatsink temperature or Tc,
Tj max,
Vce0 max,
Ic @ 30Vce
Ic @ 45Vce
Ic @100Vce
Do you want speakers limited to moderate types with phase angle <=45degrees or severe type with phase angle <=60degrees?

You probably mean the 150 watt SAP15N/SAP15P !
Problem with the SAP15N/P is their case size, accounting for a high R case-to-sink. For 200watts/4 Ohm you will need something like a 0.10-0.15 C/W heatsink to handle the max dissipation of a single pair at 45Vdc rails in 4 ohms.
The total max dissipation of the determines the power handling capability, not just the device and number.
Possible, but not economical. (it is also possible to get 200W/4 from 45Vdc rails)
Beter to invest both in output devices and heatsinks.
The economical division generally is an equal share.
