What is the optimum output power of this pairs???
 
They are the old 2SA1302/2SC3281,planning to run them at 4 ohms load too

One pair?

~70W at 4 ohms.

These are "classic transistor" and are pretty robust, Pioneer used them in alot of there amps with +/- 75VDC rails. I had a VSX 9300s 125WPC that used these babys.

These are nice transistors, but keep them within the SOA ;)

Hi,
you can get one pair of 302/281 to run from +-39Vdc supply rails into an 8ohm load, giving about 55W to 60W into 8r.
For a 4ohm load the supply rails should be kept down to +-33Vdc and can give about 60W to 65W into 4r. But the 4ohm speaker should be of a moderate rather than severe load type.
