Default 12 volts ?

Yes you can use 12 volts. The relay will take a little longer to switch. If this makes you unhappy you can reduce the value of the 330k resistor or the 470uF capacitor.

Cheers

This is the slow turn-on cct that I used for the amp. It uses a seperate small transformer to power the delay cct. It's simple (too simple?) and also provides a DC supply for other uses i.e. Fan, LEDs etc.

And the tracks ....

That's it. Using all this you should be able to build an amp that is similar to the one I completed.

The amp has just come back from another Hi-Fi nuts house (returned reluctantly after a month) and seems to be going strong.

Good Luck
