Hi all
I just wondering if someone has experience with these amp , or someone built already .
I'm planing to build these amp , so any advise would be good .
At the next week I will do the pc boards for it and buy the parts ..
If somebody know were I can purchase ECX10N16 or 20 & ECX10P16 or 20 please let me know .
I would like to use these type of lateral mosfets because a lot of fake 2SK1058 & 2SJ162 out there .
Thanks
Regards

The Profet sounds like an amplifier with an output impedance of 6.8 Ohm. Take any standard amplifier, add a 6.8 Ohm power resistance in series with the output before attempting any comparison which could'nt be fair otherwise.

It was reviewed a couple months back. The measured specs were way off from published. It fact, not very good.
I collected the parts to build a clone. But the review not not impress. Might sound great, but prefer solid state amps that measure good and sound great.

Add a 6.8 Ohm power resistor, I mean.

Can you tell us more about these J162/K1058 fakes? I wasn't aware they were being faked. Being lateral MOSFETs, the silicon in use is fairly unique and relatively easy to test even with a DVM that has a diode test setting (the low treshold makes this fairly easy).

just curious. Is the selectronic profet single ended or pp ?

Hi Vizion,
It's a four transistor push-pull amp : complementary input pair, complementary output pair

thanks forr.

Those with a sense of irony might name it a PF4.
Inspirational, a "trois hommes et un coffin" of audio.
