    Default Any suggestions on a DIY amp to put together.

    Hi all,

    I have a couple of 32-0-32 volts @ 4 Amp trafos lying around at home.

    So I thought of building an amp which can use them. Any schematics for something like this? I haven't searched on the net, maybe there are some amps out there. In terms of audio quality, the most important thing is CLEAN and BALANCED sound. We need to hear the little things!

    I was thinking to build a set of mono block amplifiers, not too fancy but nice enough for my Dynaudio Audience 42W speakers. Can someone help me point out some amplifier designs? Think I can handle a build completely from scratch.
    Regarding the power supply, with a rectifier and a 4* 10000MFD capacitor bank I get +/- 45VDC. So what is a wise decision? I estimate, with this supply you should get around 150 watts.

    Thanks In Advance

    It has to be the SKA for me... Now in the public domain for use by enthusiasts - I am yet to read a bad comment about it

    That and the fact that a well built example will thrash a Krell KSA50.

    Default F5 .... ?

    I would have a look at the Aleph J too . The F5 is not as smooth as the J , but maybe the F5's drier sound would compliment your speaker .
