R24 and R25 must be connect to +/-MV, add BAV21 in paralel with 100pF on drivers and it can work.

another H900 revolution,
this v. is good easy to find parts
how about the switching
will this be a better one?

Like this???
With only one mosfet on step driver,how much final transistor can be use???

This is OK, 4 pairs is maximum with this topology, for more outputs you must add predrivers (triple darlington) and more step mosfets.
Regards
sir mile,
if two mosfet should be use in 4 pair of output,how many mosfet in 6 pair,8 pair,how to determine step drive mosfets?

@irvynejay..sir did you build the 700 watts leach amp?im planning to build it for my sub 2 pcs 18 inches.what do you think is good for 18 inches sub,h900 by apex or the leach amp?
yes i did build it leach 700w but in 2 r witch is not good ,so far H900 is more clear and punchy to me
h900
boss apex, I have available power supply 97-48-0-48-97, can iI use that power supply for h900?
