Hello guys,
I`m wanna build my first amp. The choices are:
1- Amp based in LM3875 CI or something similar
2- AN 948 (http://www.diyaudio.com/forums/showthread.php?threadid=2236&highlight=Hex or a modifcated version http://www.diyaudio.com/forums/showthread.php?threadid=6041&highlight=AN948)
The intention is use the amp with this Preamp : http://www.normankoren.com/Audio/Spice_preamp_2.html#NewPhono (the purist version) that presently I`m building...
Which do you recommend? LM version or Mosfet?. Any advice will be apreciated.
Thanks a lot
Marcelo.

Does anyone realize that Motorolla also has a 100w/200w highperformance amp in their application notes?
Where? I can not find the Ap in the motorola web site
Thanks.
Marcelo
it is available from On Semi, the ex-Motorola semi conductor business, titled "100 and 200 watt high fidelity audio amplifier utilizing a wideband-low feedback design". It uses the 3281/1302 twin.
