300 W in 8 Ohm .

I can't build the Leach amp .. i can't find some transistors here in romania .. i relly like that amp .. well documented .. very good design .

What about the elekton amp ? someone mention about this one upper in this tread ...

Also .. maybe P68 is a good idee .

Thank's !
 
Elektor amp

The elektor amp features as follows
+-65VDC @625VA transformer
Although a Symmetrical design PA300 W
Frontend consists of Ne5534 Opamp served as diffrential amp
Voltage amplification and current drive is achieved by MJE15032 and MJE15033 drivers and output stage consists of 2 X MJ15024 and MJ15023 devices
A descent design by Riedl
Disadvantages
Requires too much heat sinking or u have to use force cooling
low slew rate
medium damping factor

here is the schematic

I have the Elektor magazine containing this article with me , But no scanner to scan the image.
Personally I would recommend u another amplifier consists of only NPN transistors at output stage because this elektor amp has not sufficient current gain to provide TRUE BASS THUMPING i.e. Its Damping factor is low.
If u are intersted then i can publish the circuit here for u
