Default Depends how many transistors you install into the output.

Also your power supply, of course can work in 4 ohms too.

Carlos

Default From now on, i would like to invite you, dear Black, and all forum friends

To go to the Dx Amplifier thread.

DXM was not aproved, so, let the thread die.

regards,

Carlos
