F5 Listening Impressions & Discussion

umut1001,

I'm sure, you can use Patrick's design with +/-24V rails, too. Just set the bias current to a lower value (max heatsink temperature 55deg or so). You will not be disappointed.

Ideally you should use 0R47 source resistors (instead of 0R22) for +/-24V 1.3A bias. It is not the optimum for the balanced configuration (not enough current), but it will work.

Do you have unbalanced schematic idea?Is there any ideal schematic for 2sk1530/2sj201.I dont have balanced soundcard.

use standard F5 schematic , just add another pair of outputs , along with their gate and source resistors .

any change in feedback resistors ?

Do you want to change the gain?

you'll have unusual 50Watts
