    Looking for great amp project..Go Here

    http://www.audioheritage.org/vbullet...3&postcount=54

    Follow this link for details, I am NOT the designer and have no affiliation with Greg Ball other than he is located in Australia.

    I do think however this design will slaughter anything commercial under US$3000 based on my auditioning including a lot of the absolute junk people around here insist on buying over on Ebay.

    My motive for building this up is to enable comfortable listening in the Australian 40+ c summer days. The intention is to build up a 300 watt version for bi amping the woofers early next month.

    Too hot for class A and in many ways its as good.

    Interesting amp.

    Hi Ian

    Thanks for the tip. I shall order a pair of GB300 PCB´s for mono blocks.
    Ian, do you know if there is any parts lists and manuals when only ordering PCB´s ?

    Regards

    You should get a pc and all parts to mount on the PCB, there is also a PS PCB and parts that go with it. Check with Greg Ball on the detail when you order.

    You will need to acquire a heat sink and transformer.

    Hi Mark.

    Here is a link

    http://members.dodo.com.au/~gregball/guru_005.htm

    The instructions advise 300va 70VCT for +/- 50 vdc but you can use a 60VCT for +/- 45 vdc or as high as 72VCT for +/-55 vdc.

    For more technical information contact Greg Ball here: [email protected]

    Calling all 4343, 4344 and 4345 owners .....This amp still impresses me.

    I played Terminator 2 Special Edition tonight loud, quite spectacular in DTS seeing and hearing steep wave fronts reproduced so cleanly and naturally.

    I think this amp has to be the amp find of the year.

    My order for the 300 watter job is going in next week.

    Thanks Ian for the update. My HT is staying the way it is but the 2 channel with the 4344's I am looking to change around. Those amps look like a nice way to power the tops in a biamp set-up.

    I'm thinking you could package the MOX electronic crossover boards and integrate the entire package.

    Ian's probably already done this by now...
